  Heredity - Wikipedia, the free encyclopedia
Heredity (the adjective is hereditary) is the transfer of characteristics from parent to offspring, either through their genes or through the social institution called inheritance (for example, a title of nobility is passed from individual to individual according to relevant customs and/or laws).
In biology, heredity refers to the transfer of biological characteristics from a parent organism to offspring, and is practically a synonym for genetics, as genes are now recognized as the carriers of biological information.
Darwin's primary approach to heredity was to outline how it appeared to work (noticing that traits could be inherited which were not expressed explicitly in the parent at the time of reproduction, that certain traits could be sex-linked, etc.) rather than suggesting mechanisms.

 Heredity - LoveToKnow 1911
The resemblances of heredity are due to the fact that the new organism takes its origin from a definite piece of the substance of its parent or parents.
The fundamental basis of heredity is the separation of a mass from the parent (germ-plasm) which under certain conditions grows into an individual resembling the parent.
The goal of the study of heredity will be reached only when all the phenomena can be referred to the nature of the germ-plasm and of its relations to the conditions under which it grows, but we have seen how far our knowledge is from any attempt at such references.

Heredity also refers to the inherited characteristics of an individual, including traits such as height, eye color, and blood type.
Heredity accounts for why offspring look like their parents: when two dogs mate, for example, they have puppies, not kittens.
The principles of heredity hold true not only for a puppy but also for a virus, a roundworm, a pansy, or a human.

 Heredity and Heritability (Stanford Encyclopedia of Philosophy)
Inheritance or heredity was a focus of systematic research before its inclusion as a key concept within evolutionary theory.
Discussions of heredity invite confusions between mechanisms responsible for individual development and mechanisms responsible for the transmission of traits from one generation to the next.
The idea that heredity is best understood as the passing on of information via DNA is expanded and defended by both biologists and philosophers including Dawkins (1976; 1981; 1985), Maynard Smith (1998; 2000a; 2000b) and Dennett (1995).

 Heredity - MSN Encarta
His work anticipated the discoveries that chromosomes are the factors that transmit heredity and that parents contribute one of each member of a pair of chromosomes to their offspring.
Darwin’s theory of heredity, known as pangenesis, attempted to account for both the process of heredity and for the variety of traits seen among offspring.
This development may drastically alter the traditional principles of heredity, opening the door to a new array of rules governing the transmission of traits from parent to offspring.

In biology, heredity refers to the transference of biological characteristics from a parent organism to offspring, and is practically a homonym for genetics, as genes are now recognized as the carriers of biological information.
In humans, defining which characteristics of a final person are due to heredity and which are due to environmental influences is often a site of controversy (the nature versus nurture debate), especially regarding intelligence and race.

heredity transmission from generation to generation through the process of reproduction in plants and animals of factors which cause the offspring to resemble their parents.
Thus the science of heredity developed long after practical observations of breeding and of parent-child resemblance had been noted and also after the theory of evolution had been established.
the popular concept of heredity was the theory of preformation: that the prototypical members of each organism (e.g., Adam and Eve among humans) contained within them all future generations, perfectly formed but in miniature, arranged one inside the next like a series of Chinese boxes.

 CATHOLIC ENCYCLOPEDIA: Heredity
The offspring tends to resemble, sometimes with extraordinary closeness, the parents; this is heredity.
This definition omits the cases of (1) alternation of generations, where the offspring resembles a more remote ancestor in the direct line, the alternation being in regular or irregular rhythm; (2) the production of neuters, like their equally neuter uncles and aunts but unlike their (fertile) parents.
Another method of explaining heredity is that which presupposes that fragments from the different portions of the body become aggregated in the sex-cells and thus become the progenitors of the different portions of the offspring.

 Darwin's precursors and influences: 7. Heredity
Sometimes Lamarck is credited (or blamed) for this opinion, but versions of it were common throughout the seventeenth and eighteenth centuries and possibly back as far as classical times and the Bible, up until the rediscovery of Mendelian genetics in 1900.
Darwin thought that particles called "gemmules" would move from the extremities where an organ was, back to the sex cells and, in modern terms, "reprogram" the sex cells with the new information.
Sometimes, this view of heredity is called Lamarckism, because in the late 19th century a group of non-Darwinian evolutionists took to calling their own views Neo-Lamarckism, meaning that genetic novelty was not random.

 Heredity
The term "genetics" was coined around the turn of the century, but much of the basic theory of genetics derives from the work of a monk who lived in Bohemia in the middle of the 19th century.
Studying a small number of easily observed traits (phenotypes), Mendel was able to deduce the existence of factors in cells that controlled their propagation from one generation to the next (we now call them genes).
Mendel's leap was to imagine that heredity consisted of unitsHereditary units could be associated with particular observable traits (e.g, those yellow peas).
