In marsupials like the opposum or kangaroo, x inactivation selectively inactivates the paternal x chromosome. a. predict the possible coat color phenotypes of the progeny of both sexes if a female marsupial homozygous for a mutant allele of an x-iinked coat color gene was mated with a male hemizygous for the alternative wild-type allele of this gene. b. predict the possible coat color phenotypes of the progeny of both sexes if a male marsupial hemizygous for a mutant allele of an x-iinked coat color gene was mated with a female homozygous for the alternative wild-type allele of this gene. c. why are the terms "recessive" and "dominant" not useful in describing the alleles of x-iinked coat color genes in marsupials? d. why would marsupials heterozygous for two alleles of an x-iinked coat color gene not have patches of fur of two different colors as did the tortoise- shell cats described in the previous problem?
