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?\nfreckles are not determined by dna.\nthere are two alleles for freckles.\nthere is no dominant allele for freckles.\nfreckles are determined by two genes instead of by one.
Answer
Answer:
B. There are two alleles for freckles.
Brief Explanation:
The fact that a child with freckles has at - least one freckled parent and can have a non - freckled sibling suggests a simple Mendelian inheritance pattern with two alleles (dominant and recessive). Freckles are determined by DNA, there is likely a dominant allele for freckles, and there's no indication they are determined by two genes instead of one.
