1 in 1700 newborns have cystic fibrosis. C is the dominant allele and c is the recessive. You must be (cc) to have the disease. Assuming Hardy-Weinberg equilibrium, how many people in a population of 10,000 would be (CC), (Cc) and (cc)?

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
