. Imagine you purchased an albino mouse (genotypecc) in a pet store. The c allele is epistatic to other coatcolor genes. How would you go about determiningthe genotype of this mouse at the brown locus? (Inpigmented mice, BB and Bb are black, bb is brown.)
In sheep, the formation of horns is a sex-influenced trait; the allelethat results in horns is dominant in males and recessive in females.Females must be homozygous for the horned allele to have horns.A horned ram was crossed to a polled (unhorned) ewe, and the firstoffspring they produced was a horned ewe. What are the genotypesof the parents?
The genetic variability of the Giddings children started out asmutations that occurred thousands of years ago. Take haircolor: Our distant ancestors probably all had dark hair, its colorcontrolled by multiple genes located on several different chromosomes.The alleles that produced Tess’s blond hair originatedas mutations in genes that control the amount and type of hairpigment. Tess probably inherited only “pale hair” alleles of all ofthese genes, so for any given hair color gene, she has the samepale hair allele on both homologous chromosomes. Chris, on theother hand, inherited both dark and pale hair alleles for at leastsome of the genes, so his homologues have different alleles. Aswe will see in Chapter 11, in many cases one allele (in this case,the dark hair allele) overrides the effects of the other allele (thepale hair allele), so Chris has black hair. What combinations ofalleles might have been packaged in Tess’s eggs and Chris’ssperm, which would combine to produce their…
