Punnett squares for each combination of parents' colour vision status giving probabilities of their offsprings' status, each cell having 25% probability in theory. The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment.
Punnett is probably best remembered today as the creator of the Punnett square, a tool still used by biologists to predict the probability of possible genotypes of offspring. His Mendelism (1905) is sometimes said to have been the first textbook on genetics; it was probably the first popular science book to introduce genetics to the public.
A punnet is a small box or square basket for the gathering, transport and sale of fruit and vegetables, typically for small berries susceptible to bruising, spoiling and squashing that are therefore best kept in small rigid containers. Punnets serve also as a rough measure for a quantity of irregular sized fruits.
Punnett squares showing typical test crosses and the two potential outcomes. The individual in question may either be heterozygous, in which half the offspring would be heterozygous and half would be homozygous recessive, or homozygous dominant, in which all the offspring would be heterozygous.
Punnett square: If the other parent does not have the recessive genetic disposition, it does not appear in the phenotype of the children, but on the average 50% of them become carriers. A hereditary carrier ( genetic carrier or just carrier ), is a person or other organism that has inherited a recessive allele for a genetic trait or mutation ...
Punnett squares for each combination of parents' colour vision status giving probabilities of their offsprings' status, each cell having 25% probability in theory. Normal text denotes a person (or chromosome from a person) who has normal colour vision and no defective gene, italics: has normal colour vision and a defective gene, and bold: is ...
