Dоsаge cоmpensаtiоn in mаmmals involves the random inactivation of one of the two X chromosomes early in development. Black fur in cats is due to an X-linked allele Xb, while the alternative allele Xo produces orange fur. Heterozygous females have a patchy black-and-orange coat color that is called "tortoiseshell." What do we call the inactivated X-chromosome? Why are the inactivated X-chromosome's genes unable to be expressed? In your answer, include what happens to the inactivated X and why this prevents expression. Using appropriate gene symbols, diagram a cross between a black male cat and an orange female cat. Give the genotypes of the parents (P1) and the phenotypes, genotypes, and ratios of all offspring in the F1.
