There Are Two Genes Known To Determine Coat Color In Sheep The Agout Gene Determines Whether Pigmentation Will Be Made 1 (590.07 KiB) Viewed 27 times

There are two genes known to determine coat color in sheep. The agout gene determines whether pigmentation will be made and where pigmentation will be located. A dominant allele, A, leads to an albino (white) phenotype and the a allele leads to a pigmented coat color determined at the brown geno. The dominant 8 allele leads to a black coat color and the recessive b allele leads to a brown coat color. a. Which gene is the epistatic gene in this scenario (agout or brown)? b. A breeder crosses two albino sheep to each other (both are heterozygous at the agouti and brown loci). What phenotypic ratio would be expected among the F1 progeny? c. A breeder crosses a black-coated female (heterozygous at the brown locus) with an albino male (heterozygous at the agouti and brown loci). What phenotypic ratio would be expected among the F1 progeny?
