Answer:
d) an offspring can inherit a recessive trait if both of its parents are heterzygous for the dominant allele.
Step-by-step explanation:
The offspring can inherit a recessive trait if both of its parents are heterzygous for the dominant allele. This mean they have one dominant trait and one recessive for the same gene.
Answer d) This means each parent has the gene Bb, when crossed Bb xBb: offspring will be 75% Bb, 25% bb. They will have a 25% probability of the recessive trait.
Answer a) Parents genes are bb x BB : offspring will be 100% Bb
Answer b) Parents genes are Bb x BB : offspring will be 50%BB-BB and 50% Bb-Bb
Answer c) Parents genes are BBxBB : offspring will be 100% BB
