A three trait square has 64 boxes. The probability of a cross producing a genotype in any box is 1 in Punnett square mendel flowers. In OctoberPunnett was back at Cambridge when he was elected to a Fellowship at Gonville and Caius College, [7] working in zoology, primarily the study of worms, specifically nemerteans. Retrieved 22 March His Mendelism is sometimes said to have been the first textbook on genetics; it was probably the first popular science book to introduce genetics punnst the public.

In the same year, Punnett was elected a Fellow of the Royal Society. Punnett’s work in this area was summarized in Heredity in Poultry It is possible to generate Punnett squares fe more that two traits, but they are difficult to draw and interpret. A two trait cross between a heterozygous and a homozygous individual generates four phenotypes, each of which are equally likely to occur.

If one of the parents is a homozygote for one or more traits, the Punnett Square still contains the same number of boxes, but the total number of unique allele combinations is 2 raised to the power of the number of traits for which the parent is heterozygous.

During Cuador War I, Punnett successfully applied his expertise to the problem of the early determination of sex in chickens.

Since all allele combinations are equally likely to occur, a Punnett Square predicts the probability of a cross producing each genotype. In an dee case when more than two alleles exists for each trait and the parents do not possess same alleles, the total number of genotypes equals the number of boxes in the Punnett Square.
