Tay-Sachs disease is caused by an autosomal recessive allele. The disease is characterized by mental deficiency and blindness, with death occurring by four years of age. The incidence of the disease among newborns is about 10 per million births. Assuming Hardy-Weinberg equilibrium, estimate the frequency of the allele and of the heterozygotes.

Punnett squares are used to show possible combinations of alleles or to predict the probability of a trait occurring in offspring. an incomplete dominance cross is performed between a bird that is homozygous for red feathers and a bird that is homozygous for blue feathers. purple offspring result. then, two of the purple offspring are crossed. according to the punnett square for this cross, how many of the offspring from the second cross will have a feather color that results from incomplete dominance? 1 in 4 2 in 4 3 in 4 4 in 4
