L7: In humans, a common form of colorblindness is caused by mutations at a gene located on the X-chromosome. Consequently, males are much more likely to exhibit this form of colorblindness than are females. Which type of inheritance is this?

L6: Labradors can be black, brown or yellow, and their coat color depends on two loci. One determines coat color, with black (B) dominant over brown (b). Another locus determines deposition of color in the fur, with color deposition (E) is dominant over no color deposition (e). You cross a black Labrador homozygous for both traits with a yellow Labrador. What are the genotypes and phenotypes of the expected progeny?

L5: Fast-feathering is a Z-linked, recessive trait. The dominant trait is slow-feathering. A fast-feathering male is crossed to a slow-feathering female. What percentage of female chicks will be fast-feathering? Note: in birds, the females are the heterogametic sex.
