Presentation transcript:

One cat carries heterozygous, long-haired traits, and its mate carries homozygous short-haired traits. Use a Punnett square to determine the probability of one of their offspring having short hair.

In purple people eaters, one-horn is dominant and no horns is recessive. Draw a Punnett Square showing the cross of a purple people eater that is hybrid for horns with a purple people eater that does not have horns. Summarize the genotypes & phenotypes of the possible offspring.

One flower is heterozygous red and it is crossed with a homozygous white plant. Use a Punnett square to determine the probability of one of their offspring having a red color.

A homozygous dominant brown mouse is crossed with a heterozygous brown mouse. (tan is the unexpressed color)

Offspring Genotypes are TT, Tt, and tt Phenotypes: T= Ticklish Using the information below. Work backwards and tell me what each parent’s alleles are on the Punnett Square. Then give the probabilities of each genotype and phenotype. Offspring Genotypes are TT, Tt, and tt Phenotypes: T= Ticklish t= not ticklish
