Question 2

Some dogs have erect ears; others have drooping ears.Some dogs bark when following a scent; others are silent.Erect ears and barking are due to dominant alleles located on different chromosomes.If two dihybrids are crossed,

Accepted Answer

A) the most common phenotype is drooping ears and barking. 
B) all droopy-eared, silent offspring are pure-breeding. 
C) the least common phenotype is drooping ears and barking. 
D) there will be no phenotypes or genotypes that resemble the original parents. 
E) there will be no offspring that resemble the F1 generation. 
A) the most common phenotype is drooping ears and barking. 
B) all droopy-eared, silent offspring are pure-breeding. 
C) the least common phenotype is drooping ears and barking. 
D) there will be no phenotypes or genotypes that resemble the original parents. 
E) there will be no offspring that resemble the F1 generation.

Question 3

An incompletely dominant gene controls the color of chickens so that BB produces black, Bb produces a slate-gray color called blue, and bb produces splashed white.A second gene controls comb shape, with the dominant gene R producing a rose comb and r producing a single comb.If a pure-breeding, black chicken with a rose comb is mated to a splashed-white chicken with a single comb in the F2 generation, what fraction of the offspring will be black with rose comb?

Accepted Answer

A) 9/16 
B) 3/8 
C) 3/16 
D) 1/8 
E) 1/16 
A) 9/16 
B) 3/8 
C) 3/16 
D) 1/8 
E) 1/16
