Suppose you discover a mouse that has spiky fur instead of the usual soft fur.You notice that this trait seems to be present only in males.To investigate this pattern, you cross a spiky-fur male with a soft-fur female, and find that all the F₁ progeny of both sexes have soft fur.You then interbreed the F₁ and observe that all the F₂ females have soft fur, but 1/4 of the F₂ males have spiky fur.You conclude that the spiky allele is A)an X-linked recessive. B)Y-linked. C)autosomal recessive with sex-influenced expression. D)an X-linked dominant. E)an autosomal dominant with sex-influenced expression.
