some people have freckles, and some people do not have freckles. if a child has freckles, at least one parent has freckles. however, the child may have a sibling that does not have freckles. which statement best describes the presence of freckles?\no freckles are not determined by dna.\no there are two alleles for freckles.\no there is no dominant allele for freckles.\no freckles are determined by two genes instead of by one.
Answer
Brief Explanations:
If a child has freckles and at least one parent has freckles, and a sibling may not have freckles, this indicates a simple - inheritance pattern. In simple inheritance, there are usually two alleles for a trait. Freckles are determined by DNA, and there is a dominant allele for freckles. There is no indication that two genes are involved; it is likely a single - gene trait with two alleles.
Answer:
There are two alleles for freckles.
