Briefly describe a type of variation you observed within your most abundant OTU (here we are asking about differences that you noticed among individual specimens from the same "species"). How could you determine experimentally whether that variation is because of genetic differences, differences in the environment each organism experiences, or some combination of the two.

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
