While working with a type of beetle that is normally smooth, large, and white, you discover three mutations that lead to the recessive phenotypes bumpy, small, and grey, respectively. You cross true-breeding smooth white beetles to true-breeding bumpy grey beetles and get all smooth white F1 beetles. Then you cross.

White eyes in Drosophila melanogaster result from an X-linked recessive mutation. Occasionally, white-eyed mutants give rise to offspring that possess white eyes with small red spots. The number, distribution, and size of the red spots are variable. Explain how a transposable element, or transposon, could be responsible for this spotting.

White belly color in cats is controlled by an automsomal locus as follows: AA-lots of white on underside Aa a little white on feet and chin aa-no white A pair of x-linked alleles control coloration in the non-white portions of the coat. One allele causes orange color and the other causes black color. Heterozygotes.
