Sagot :
The correct answer is the proportion of the progeny with exactly one dominant allele = (4/16)
Because AaBb plants self-fertilize, AaBb
AaBb
In this case, A has dominance over a while B has dominance over b.
Four distinct gametes—AB, Ab, aB, and ab—will be produced from each AaBb genotype.
Thus, if we perform the Punnett square
AB Ab aB ab
AB AABB AABb AaBB AaBb
Ab AABb AAbb AaBb Aabb
aB AaBB AaBb aaBB aaBb
ab AaBb Aabb aaBb aabb
There will be four genotypes: Aabb, aaBb, Aabb, and aaBb, each of which will have exactly one dominant allele.
Therefore, the answer is the proportion of the progeny with exactly one dominant allele = (4/16)
