How can an offspring inherit a recessive trait?

a) an offspring can inherit a recessive trait if one of its parents has the trait and the other is homozygous for the dominant allele
b) an offspring can inherit a recessive trait if one of its parents is heterzygous for the recessive allele and the other is homozygous for the dominant allele
c) an offspring can inherit a recessive trait if both of its parents are homozygous for the dominant allele
d) an offspring can inherit a recessive trait if both of its parents are heterzygous for the dominant allele

"An offspring can inherit a recessive trait if both of its parents are homozygous for the dominant allele" is the one among the following choices that gives the correct answer. The correct option among all the options that are given in the question is the third option or option "c". I hope the answer helped you.

Answer:

d) an offspring can inherit a recessive trait if both of its parents are heterzygous for the dominant allele.

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
