An agouti mouse that is heterozygous at the agouti and albino loci (aacc) is mated to an albino mouse that is heterozygous at the agouti locus (aacc). allele definitions: a_ = agouti if non-albino aa = black if non-albino c_ = non-albino with a/a gene determining phenotype cc = albino independent of a/a gene genotype.

what percentage of the progeny do you expect to be albino?

what percentage of the progeny do you expect to be agouti?

what percentage of the progeny do you expect to be black?

Percentage albino = 37.5%

Percentage agouti = 37.5%

Percentage black = 25%

Explanation:

The cross is between AaCc and Aacc.

The presence of C_ makes A_ to be agouti.

The presence of C_ makes aa to be black.

The absence of C makes A_ and aa to be albino

AaCc   x   Aacc

Offspring:

2 AACc     Agouti

2 AAcc     Albino

4 AaCc     Agouti

4 Aacc      Albino

2 aaCc      Black

2 aaCC      Black

Percentage albino = 6/16 x 100% = 37.5%

Percentage agouti = 6/16 x 100% = 37.5%

percentage black = 4/16 x 100% = 25%
