Start with the p generation with the following genotypes (aa x aa). based on classical mendelian inheritance, how will a cross between two homozygous parents, one dominant and one recessive, influence future generations?
a) the f1 generation will show an even split between the dominant phenotype and the recessive phenotype.
b) the f1 generation will all show the dominant trait and future crosses will continue to produce genotypes expressing the dominant trait.
c) although the f1 generation will all show the dominant trait, the offspring will all be heterozygous and increase chances of future variation.
d) the f1 generation will show a mix of the dominant phenotype and recessive phenotype and over generations the recessive trait will increase in number.

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
