Question

Which is the most likely explanation for a child exhibiting a heritable trait that neither parent exhibits? (1 point)

A grandparent exhibits the trait, and the child inherited it directly from that person

A mutation occurred, and the child exhibits a new trait due to the mutation

The trait is recessive, and the child inhented a recessive allele from each parent.

The parents have recessive alleles, and the child inherited a dominant allele

- I chose C, is that correct?

Answer 1

The parents have recessive alleles, and the child inherited a dominant allele.

Answer 2

Yes, your choice C is the most likely explanation for a child exhibiting a heritable trait that neither parent exhibits. When a child exhibits a trait that is not seen in either of their parents, it typically indicates that the trait is recessive, and the child has inherited a recessive allele from each parent. This means that both parents carry the recessive allele for the trait, but do not exhibit the trait themselves. When two carriers of a recessive trait have a child, there is a 25% chance that the child will inherit the recessive allele from both parents and exhibit the trait. Therefore, choice C is the most reasonable explanation in this scenario.

Answer 3

Yes, you are correct. The most likely explanation for a child exhibiting a heritable trait that neither parent exhibits is option C: The trait is recessive, and the child inherited a recessive allele from each parent. In this case, both parents would be carriers of the recessive allele but do not show the trait themselves. However, when both parents pass on a recessive allele to their child, the child will exhibit the trait.
