The chart below shows several species found in a pond ecosystem and the ph levels in which the species can survive. the normal ph of the pond is 6.5. if the ph of the pond fell to 5.0 due to acid rain, which of the species shown in the chart would die?

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
