In guinea pigs, black fur (B) is dominant to white fur (b). If a black female guinea pig mates with a white male guinea pig and half of the offspring are black then--
the black female guinea pig was heterozygous
100% tall
aa
TT x Tt
Rr x rr
1 BB : 2 Bb : 1 bb
AA
both trait and phenotype are correct
In plants, tall (T) is dominant to short. If a homozygous tall plant is bred with a heterozygous plant. What is the predicted phenotypic ratio of the offspring?
the black female guinea pig was heterozygous
100% tall
aa
TT x Tt
Rr x rr
1 BB : 2 Bb : 1 bb
AA
both trait and phenotype are correct
