Mutations are sudden changes that may occur in a gene or chromosome. These changes may affect the way traits are inherited. If a mutation occurs in a body cell, such as a bone cell, the mutation affects only the organism that has it. If the mutation occurs in a sex cell, then it can be passed on to an offspring. Some mutations are helpful and can be desirable in an offspring. Determine whether each item below is part of the human life cycle, the cell cycle, or both.

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
