In humans, red-green color blindness is recessive and X-linked, whereas albinism is recessive and autosomal. What types of children can be produced as the result of marriage between two homozygous parents, a normal-vision albino woman and a color-blind, normal male?

In Drosophila, an X linked recessive mutation, scalloped (sd), causes irregular wing margins. Diagram the F1 and F2 results if a (a) scalloped female is crossed with a normal male; (b) a scalloped male is crossed with a normal female (assume the female is homozygous). Compare these results to what you would find if the trait was not sex linked.
