Hydrangeas are flowers that can produce either pink flowers or blue flowers. your neighbor thinks that the color of the flowers are determined by the type of soil in which the hydrangeas are grown. your friend thinks the color is determined by the plants alleles. how could you perform an experiment to prove which hypothesis best explains how the flower color of hydrangeas is determined.

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
