		Reginald Punnett and William Bateson were among the first English geneticists.
		Punnett devised the "Punnett Square" to depict the number and variety of genetic combinations, and had a role in shaping the Hardy-Weinberg law.
		Punnett was a quiet, tolerant, cultured man who was excellent at all sport involving a small fast ball.

	Reginald Punnett - Wikipedia, the free encyclopedia
		Punnett was also the creator of the Punnett square, a tool in genetics which is still used by biologists today to predict the probability of possible genotypes of offspring.
		Punnett became the first Arthur Balfour Professor of Genetics at Cambridge, when Bateson left Cambridge in 1912 and was elected a Fellow of the Royal Society in the same year.
		Punnett received the society's Darwin Medal in 1922.

	Mathematics and the Genome
		Reginald Punnett (1875-1967) is known for the Punnett square, which is a diagram that is useful in understanding the results of mating organisms with different possible genotypes.
		In the audience was George Udney Yule (1871-1951), who claimed to Punnett that if a particular allele was dominant that the frequency of this allele would grow until it reached.5; thereafter one would have stability which was consistent with the standard Mendelian observation that phenotypes were seen in the ratio of 3 to 1.
		Punnett thought this reasoning was not correct and took the problem to Hardy.

	Punnett Squares
		A Punnett square is a chart which shows/predicts all possible gene combinations in a cross of parents (whose genes are known).
		Punnett squares are named for an English geneticist, Reginald Punnett.
		Using Punnett Squares, you can predict the genotypes and phenotypes of the offspring of a cross between a homozygous (purebred) tall pea plant and a homozygous (purebred) short pea plant.

		A Punnett Square is a chart that provides a means of predicting all the possible outcomes for combining genes in a cross between parents whose genes are known.
		Reginald C. Punnett, a British mathematician/biologist who worked at the University of Cambridge during the last century, designed the Punnett Square.
		As described earlier, a Punnett Square is a chart that allows one to predict the possible outcomes when combining genes of two sexually compatible individuals.

	Punnett \| Reginald Crundall \| 1875-1967 \| geneticist and professor of biology, University of Cambridge
		Reginald Crundall Punnett ( 1875-1967) was introduced to biology during a bout of childhood appendicitis, when he read a series of books on the subject that his father had bought because of their elegant binding.
		Punnett was a believer in the theories put forward by obscure monk Johann Gregor Mendel ( 1822-1884), the founder of modern genetics, and wrote the first textbook on the subject.
		Punnett was also the inventor of the "Punnett Square", which depicts the number and variety of genetic combinations.

	Punnett
		At the age of nine, Reginald Crundall Punnett, the eldest son of a middle-class builder, suffered a bout of appendicitis.
		Punnett's interests also included the investigation of butterfly mimicry, the notion of one species mimicking another for adaptive advantage.
		Encouraging practical applications of genetics, Punnett served as an expert on poultry breeding during World War I. As wartime food shortages demanded economical measures, Punnett used sex-linked plumage colors to breed chickens of different colors according to sex.

		Named for the British geneticist Reginald Punnett, a Punnett Square is useful for predicting the results of breeding.
		Notice that in the Punnett Square (Figure 1), the symbols for all the possible alleles carried by the male (sperm) are arranged along the top of the square, while all the possible alleles carried by the female are listed on the side.

	Introduction
		Reginald Punnett developed a method to analyze data from genetic crosses that is particularly useful where small numbers of genes are involved.
		The Punnett square is a good visual representation of all possible genotypic and phenotypic outcomes for a given cross.
		When higher order crosses (dihybrid, trihybrid, and tetrahybrid crosses) are done, the dimensions of the Punnett Square increase and this method of analyzing genetic data becomes unwieldy.

	2 Breeding Experiments: Gametic Crosses
		The pioneer Mendelian geneticist Reginald Punnett developed a device known as the Punnett square, which he found useful in teaching Mendelian genetics to Cambridge undergraduates, that gives the proportions of genotypes that will arise when these gametes unite at random.
		A simple usage of the Punnett square is shown in Table 3.1 for the mating of two heterozygous parents in a two-allele system.
		For our purposes the genotypic frequencies from the Punnett square are important because they allow us to calculate the simple first and second moments of the phenotypic distribution that result from genetic effects; namely, the mean and variance of the phenotypic trait.

		In lieu of costly universal screening programs for such diseases as diabetes, hypertension, and colon cancer, scientists now believe that simple Punnett Square analysis can accurately predict which individuals are likely to develop certain conditions, thereby allowing selective screening in these individuals.
		Maynor and his colleagues argue that Punnett Square analysis is simple and inexpensive, and involves only seconds of a physician's time, making it "the ideal screening tool for today's managed care environment."
		The Punnett Square has been used for decades to demonstrate inheritance of traits in normal and wild-type peas and other legumes.

	ILLEGAL COPY of PRINCIPLES of GENETICS!!! (Site not responding. Last check: 2007-11-03)
		Punnett thought that a dominant trait should dominate a population but he was confusing the genetics of populations with the genetics of individuals.
		Hardy was quick to see that a Punnett square was no way to approach a population problem so he set out to find a way to better understand the genetics of populations.
		Punnett understood that - he was constantly lining up the gametes along the edges of his squares then fusing them into diploid zygotes.

	Basic Principles of Genetics: Probability of Inheritance
		It does not matter which parent is on the side or the top of the Punnett square.
		Each of the two Punnett square boxes in which the parent genes for a trait are placed (across the top or on the left side) actually represents one of the two possible genotypes for a parent sex cell.
		Punnett squares are standard tools used by genetic counselors.

		Natural selection is a real factor in connection with mimicry, but its function is to conserve and render preponderant an already existing likeness, not to build up that likeness through the accumulation of small variations, as is so generally assumed.
		My view, which I share with Leo Berg, Pierre Grasse and Reginald Punnett, is that Natural Selection is now and never was a creative force but was rather a conservative element serving only to maintain the status quo.

		Reginald Punnett, in his book “Mimicry in Butterflies” offered a similar appraisal of the environment (Natural Selection) in 1915:
		I think Punnett's use of the word "preponderant" is perfectly straightforward and requires no further interpretation.
		As for my "assertions" as you describe them, they are largely summaries of evidence from the fossil record and the laboratory bench none of which will ever be reconciled with the Darwinian paradigm.

	Social Origins of Eugenics
		A chapter on human genetics in Reginald Punnett's book, Mendelism (1911), described the Mendelian inheritance of brachydactyly, hemophilia, and color blindness.
		However, Punnett acknowledged how difficult it is to study the inheritance of intelligence and other behavioral characteristics, which eugenicists believed had the greatest impact on society.
		Francis Galton had aroused interest in the inheritance of behavioral traits in his book Studies of Hereditary Genius (1869), which purported to show a high proportion of eminent men in aristocratic British families.

	Gregor Mendel's Legacy
		A diagram called a Punnett square (named after Reginald Punnett!) can be used to predict the outcomes of such a cross.
		Predicting the results of a dihybrid cross is rather more complicated than a monohybrid cross because one needs to consider all the possible combinations of the two alleles for the two traits in each parent's gametes and then all the possible gamete combinations at fertilization.
		A Punnett square is again used and if students recognise that the most complex dihybrid cross requires a 4x4 (16 cell) Punnett square for the offspring, with plenty of practice all possible dihybrid cross questions become easy.
