2. in consideration of the following genetic cross: xbxb x xby color blindness is a recessive trait (b) and normal vision is dominant (b). if the parents above had children: a. what is the possibility of them having a son that is color blind? b. what is the possibility of them having a daughter that is color blind? c. what would the genotypes have to be in order for them to have a color blind daughter?

Based on the law of dominance, we would expect percent of the offspring from this cross to have large teeth.

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
