(06) A grey rat, heterozygous for both traits is mated with a black rat heterozygous for pigmentation. What are the offspring? Give the phenotypes after drawing the punnet square

Answer:
If a gray rat heterozygote (Gg) and a black rat heterozygote (Bb) were to breed, the following phenotypic and genotypic ratios would result:
ExplanatioN
Gg (Heterozygous gray rat) X Bb (Heterozygous black rat)
B b
G GB Gb
g gB gb
therefore, In offsprings, 50 % rats will be gray and 50 % rats will be black. So, both the ratios (phenotypic and genotypic) would be 50:50
