Coat color of lab retrievers is determined by two loci. Labs with genotype B_E_ are black, labs with genotype bbE_ are chocolate, and labs with genotype _ _ee are yellow. The dashes in these genotypes indicate that either allele could be substituted without changing the phenotype. A. Which of the following are possible coat colors for the parents of Ottoman, a black lab? (Circle all the correct answers)

a. Black

b. Chocolate

c. Yellow

B. Which of the following gene actions exist(s) for this two loci (i.e., locus B and locus E)? (Circle all the correct answers)

a. Dominance

b. Epistasis

c. Additive

d. None of the above

UESTION 4 Background info: in Labrador retrievers there is a gene, called black that participates in determining coat colour. This gene has two alleles, B and b. There are two other genes that participate in determining coat colour in Labs: the extension gene (with alleles E and e) and the agouti gene. All Labs are homozygous mutant for the agouti gene (so we can ignore this gene in our analyses and in our predictions, because it is not a variable)....

1. Labrador retrievers come in several colors: brown, black, or yellow. In a cross of a black female with a brown male, results can be either all black puppies, 1/2 black to 1/2 brown puppies, or 3/4 black to 1/4 yellow puppies. What to these results indicate?        A. Yellow is dominant to black.         B. Black is dominant to brown and to yellow.         C. Brown is dominant to black.         D. There is incomplete...

Alleles at two gene loci influence % protein in pea leaves. Each locus assorts independently. There are two alleles at each locus; alleles A and a at locus 1, and alleles B and b at locus 2. Each upper-case allele (e.g. “A”) has an additive and cumulative effect that increases the % protein by the same amount (20%) for each upper-case allele contained in an individual. The upper-case alleles are the “contributing” alleles. There are no interlocus interactions and no...
