In humans, the trait of freckles exhibits simple mendelian inheritance patterns. the allele for freckles is dominant (f), and the allele for no freckles is recessive (f). an individual who is heterozygous for freckles would have which of the following phenotypes?

Ff (With freckles)

Explanation:

A gene can exist in contrast forms called alleles. In a gene, one allele is capable of masking the expression of another. The allele masking is called the DOMINANT allele while the allele being masked is called the RECESSIVE allele.

Heterozygosity means the organism has two different forms (alleles) of a gene from each parent i.e. a combination of the dominant and recessive allele.

Since the possession of freckles (F) is dominant over no freckles (f). In an heterozygous state (Ff), the dominant allele (F) will mask the expression of the recessive one, hence the presence of freckles will be phenotypically expressed.
