Answer :
Well, if one wolf is Homozygous for the dominant G allele, then it will be GG. One is heterozygous, meaning it’s Gg. So in a punnet square you’ll end up with GG,GG,Gg,and Gg. Since heterozygous also holds that dominant trait, it works as if it were a GG. The answer is 100%

Final answer:
In a cross between homozygous dominant (GG) and heterozygous (Gg) grey wolves, 100% of the offspring are expected to have grey hair, thanks to the dominance of the grey hair allele.
Explanation:
In this case, we are dealing with hereditary traits in Alaskan wolves specifically related to hair color. The information provided tells us that the allele for grey hair (G) is dominant to the allele for brown hair (g). When crossing two grey wolves, one of which is homozygous for grey hair (GG) and the other is heterozygous (Gg), we use a Punnett Square to determine the possible genotypes of their offspring.
The Punnett Square for these parents would look like this:
- Top row: G (from GG parent), G (from GG parent)
- Left column: G (from Gg parent), g (from Gg parent)
The results of the cross yield: GG, Gg, GG, Gg. Therefore, because both GG and Gg wolves display the grey hair color due to the dominance of the G allele, we conclude that 100% of the offspring are predicted to have grey hair.
