Question

anita thinks that she has heterozygous alleles for red hair. if she is correct, which of these diagrams best illustrates anitas alleles for red hair?

Explanation:

Heterozygous alleles mean that an individual has two different alleles for a particular gene. In genetics, if we consider the allele for red - hair, let's assume the dominant allele is \(R\) and the recessive allele is \(r\). For a heterozygous condition, the individual should have one dominant and one recessive allele.
The first diagram shows two \(R\) alleles (homozygous dominant), and the second diagram shows one \(R\) and one \(r\) allele (heterozygous).

Answer:

The second diagram (with \(R\) and \(r\) alleles) best illustrates Anita's heterozygous alleles for red hair.
