Answer:
100% black
Explanation:
<em>The allele for black is dominant over that of the grey fur.</em>
Let B represents the allele for black color and b for grey color.
Homozozygous black rabbit will have the genotype: BB
Heterozygous black rabbit will have the genotype: Bb
If the two are crossed;
BB x Bb
Offspring: BB, Bb, BB, and Bb = 2BB and 2Bb
2BB = Black fur
2Bb = Black fur (heterozygous)
Both BB and Bb offspring are black phenotypically.
<em>Hence, all the offspring will appear black, a phenotypical ratio of </em><em>100% black.</em>
