In humans, having dimples is a dominant trat. In order for a child to have dimples
A. at least one parent must not have dimples and pass on the recessive allele.
B. both parents must not have dimples and pass on the recessive allele.
C. both parents must have dimples and pass on the dominant allele.

Correct.
Thank you i tried to say thank you on my last post but it wouldnt let me.
You're very welcome.

Yes, the correct answer is D. In order for a child to have dimples, at least one parent must have dimples and pass on the dominant allele.
To understand this concept, we need to know the basics of dominant and recessive alleles. Alleles are alternative forms of a gene that occupy the same position on a specific chromosome. In the case of dimples, there are two possible alleles: one for dimples (dominant) and one for no dimples (recessive).
Dominant alleles are expressed whenever they are present. So, if an individual has the allele for dimples, they will likely have dimples themselves. On the other hand, recessive alleles are only expressed when an individual inherits two copies of the recessive allele. Therefore, if both parents do not have dimples, they will not pass on the dominant allele for dimples to their child.
However, if at least one parent has dimples, they must carry at least one dominant allele for dimples. Even if the other parent does not have dimples and passes on a recessive allele, the child will inherit one dominant allele for dimples and thus have the trait.
In summary, the answer is D - at least one parent must have dimples and pass on the dominant allele.
