  The Effects of Interbreeding on the Morphological and Genetic Attributes of Non-human Primates / Beth Christine Laas
The observation of these two species interbreeding led to study of further inter-species breeding in captivity, such as the gibbon and siamang or the baboon and rhesus monkey.
Nagel believed the primary motivation behind the interbreeding was the abduction of anubis females by hamadryas males (Nagel: 1973).
In order to further explore the explanations behind nonhuman primate interbreeding in the wild, it is necessary to evaluate the social behavior of the animals as well as the environmental conditions when it occurs.

  THE RELATIONSHIPS AND EVOLUTION OF THE DENDROICA CORONATA COMPLEX
The analysis of interbreeding between coronata and auduboni is based primarily on six plumage characters of breeding-plumaged males, wing pattern, tail pattern, throat color, auricular color, and the presence or absence of a supraloral spot and postocular line.
Interbreeding in northwestern British Columbia probably occurs in the upper reaches of the valleys o.f the Iskut-Nass and perhaps $keena- $tikine Rivers.
MATERIALS AND METIODS The study of the interbreeding of coronata and audubonl was preceded by an in- vestigation of plumage and mensural variation of the D. coronata complex outside the area of southeastern Alaska, British Columbia, and Alberta (Hubbard, 1967).

 PROPOSED INTERBREEDING PROGRAMME BETWEEN MINIATURE BULL TERRIERS AND BULL TERRIERS
The main purpose of the Interbreeding Programme is to reduce the frequency of PLL in the Miniature Bull Terrier.
One generation of interbreeding will not reduce the frequency of the PLL gene sufficiently and whatever reduction is achieved will be quickly diluted out by mating progeny of an interbreed back to Miniature Bull Terriers.
Those taking part in the Interbreeding Programme are reminded that although health screening may identify the presence of certain conditions at the time of testing, it does not guarantee that later onset will not occur.

 Interbreeding   (Site not responding. Last check: 2007-11-02)
Interbreeding is currently undertaken in Australia and the United Kingdom.
One generation of interbreeding will not reduce the frequency of the PLL gene sufficiently and whatever reduction is achieved will be quickly diluted out by mating progeny of an interbreed back to Bull Terriers (Miniature).
Although interbreeding has been specifically introduced to reduce the incidence of Primary Lens Luxation (PLL) within Bull Terrier (Miniature), breeders are strongly recommended to be selective in their choice of Bull Terrier, particularly in regard to size and bull-terrier type.

 Timberjay Newspapers Online
Biologists on the Superior National Forest say they have found evidence that lynx and bobcat may be interbreeding in Minnesota— a finding that appears to be the first documented case of lynx-bobcat hybridization in the wild.
In most cases, lynx and bobcat interbreeding is kept to a minimum, mainly because the two species are separated by range.
The interbreeding would appear to add more evidence to the contention by Lindquist and others that lynx are actively breeding in Minnesota.

 Interbreeding Between Species   (Site not responding. Last check: 2007-11-02)
In fact, the afrocentrist position, that there was only a SINGLE gene pool, is a stronger statement of their capability for interbreeding than mine.
Note how 'shifty' Wolpoff is. As a multiregionalist, he argues that "gene flow" (interbreeding) between advanced populations (who are called sapiens because of their clearly more-modern morphology) and less-advanced (erectus 'grade') specimens caused all the world's 'people' to evolve into sapiens.
The important point, with respect to interbreeding of species, is that hominin species separated by several million years of divergence can still produce fertile hybrid offspring.

 The Antiquity of Man Homo interbreeding
This mechanism is investigated using a quantitative model that suggests explanations for many puzzling aspects of the genetic, fossil, and archaeological data on modern human origins.
This model emphasizes that genetic interchange among human populations, facilitated both by gene flow and range expansions coupled with interbreeding, has been a major force in shaping the human species and its spatial pattern of genetic diversity.
Moreover, living humans are still polymorphic for `modern' traits, and the frequencies of different `modern' traits show heterogeneity in their present geographical distributions1.

 1000 years of interbreeding   (Site not responding. Last check: 2007-11-02)
In 1941 Harrison Matthews stated that hybrids tend to be smaller and as far back as 1896, naturalist Edward Hamilton suggested that the true Wildcat was being supplanted by hybrid "mongrel" Wildcats.
His suggestion of a "self-perpetuating strain of notably large hybrids" is unrealistic, since continued interbreeding will restore the smaller sized "norm".
Likewise the suggestion that non-native genes will lead to an "unpredictable addition to the British ecosystem" is faulty since the wild influence is diluted by interbreeding with the native population.

 Interbreeding Hamster Species
However, interbreeding of the two species is not recommended as it is not in the interests of either species to do so.
It is worth noting that although the two species have many similiarities they do not occupy the same ranges in the wild and so no interbreeding of the two species occurs in the wild.
Therefore interbreeding the two in captivity is unnatural.

The interbreeding hypothesis contrasts with at least one prominent theory that posits that no interbreeding occurred when the two species encountered one another.
This copy subsequently spread in humans from a single copy when it first crossed into humans to an allele that is now present in an estimated 70 percent of the population worldwide today.
And the other states that extensive interbreeding did take place and that modern humans evolved from that interbreeding in many regions of the world.

 Extensive interbreeding occurred among multiple matriarchal ancestors during the domestication of dogs:
The dog, Canis familiaris, is the only member of the family Canidae, and is the "oldest" animal that can be fully domesticated in the world, since the historical evidence showing its strong connection with humans can be traced back to the far preagricultural age (Turnbell and Reed, 1974).
Domestic dogs were excluded from this test, since we considered that the exclusion would eliminate any bias caused by artificial intra- and interbreeding in the dog populations.
We inferred, therefore, that the domestication from wolves to dogs occurred in several (at least two) places, and that the domestic dog may be derived from two wolf populations separated geographically (north and south).

 Biocompare News - Could Interbreeding Between Humans And Neanderthals Have Led To An Enhanced Human Brain?
The new research, which was published online during the week of November 6, 2006, in the early edition of the Proceedings of the National Academy of Sciences (PNAS), suggests that human evolution was not just a matter of spontaneous advantageous mutations arising within the human lineage.
Human evolution may also have been influenced by interbreeding with other Homo species, which introduced gene variants, known as alleles, that are beneficial to human reproductive fitness, said the study's senior author Bruce T. Lahn, a Howard Hughes Medical Institute researcher at the University of Chicago.
Lahn said the group's data suggest that the interbreeding was unlikely to be a thorough genetic mixing, but rather a rare - and perhaps even a single — event that introduced the ancestral D allele previously present in this other Homo species into the human line.

 The Florida Panther Society, Inc.
The drastic fragmentation of habitats in the past 100 years and the extinction of some subspecies such as the Eastern cougar isolated the Florida panther and cut off its corridors to other subspecies.
Now, in an effort to strengthen the Florida panther populations, a limited number of Texas cougars will soon be introduced in a government-sponsored interbreeding program in southern Florida.
Results of the Interbreeding Program will be evaluated over the next several years.

 Line Breeding and Interbreeding.
Inbreeding (not interbreeding, that is a different thing altoghether) is the mating of close relatives such as brother to sister, mother to son, father to daughter.
Interbreeding is cross breeding, or do you mean inbreeding? ; If the latter then the difference is just the degree.  Generally mating relatives that would be considered incestuous in human terms would be Inbreeding Mother son, grnaparent Grandchild bother and sister.

 Caste-off orangs: controversy surrounds implications of a hybrid label - interbreeding Sumatran and Bornean orangutans ...
The organization's 55 member zoos and primate conservation centers with orangutans all adopted the policy, though some "accidental" births did occur through 1991, observes Lori A. Perkins, a conservation biologist at Zoo Atlanta who coordinates AZA's species survival plan for orangutans.
Perkins says Seuanez interpreted the inversion as suggesting that orangutans on the two islands represent distinct subspecies "that had evolved over at least 1,000 generations of separation." Soon, a debate erupted among orangutan conservators.
The other side decried this suggestion as racist, arguing instead that the animals constitute a single breed, recalls geneticist Oliver A. Ryder of the Zoological Society of San Diego.

 Homo Erectus And Homo Sapiens Did Little Interbreeding
An international study of Y chromosomal DNA shows that East Asian populations migrated out of Africa and suggests that little or no interbreeding of Homo erectus and Homo sapiens occurred after the migration.
Shriver warns, however, that there are some ways in which this result could be accurate even though interbreeding took place.
If all of the Y chromosomes inherited from Homo erectus were eliminated from the population because those with Homo erectus ancestors were swept from the population due to a disease to which they were especially susceptible, they would not appear in the sample.

 Neanderthals
Most anthropologists seem to accept the conclusion of molecular evolutionists that the recently obtained sequences of Neanderthal mitochondrial DNA prove that Neanderthals and Cromagnons did not interbreed, even though they lived close together in some places for thousands of years.
If there were some interbreeding, and if it were generally the case that the husband moved to join the race of his wife, the Neanderthal mitochondrial DNA would have disappeared from the European gene pool in the long run, but Neanderthal nuclear DNA would have been permanently taken into the European gene pool.
Therefore the first molecular geneticist to find Cromagnon mtDNA in a fossil that looks predominantly Neanderthal but with some Cromagnon admixture will be the first to have proved that the two human types did interbreed.
