Answer:
The presence of freckles in a individual, or predisposition to have them, is a trait that is inherited with an autosomal dominant pattern, and is not related to sex-linked inheritance.
Explanation:
Freckles are accumulations of melanin in the skin, which form small reddish or light brown spots, predominantly in white-skinned people.
<u>
The melanocortin receptor gene</u> undergoes a change that gives rise to a variant - which is phenotypically expressed in the presence of freckles - whose inheritance has been determined to be autosomal dominant.
<u>Under no circumstances is the transmission of the gene that determines the presence of freckles linked to sex</u>, because is an autosomal trait, as is hair, eye or skin color.
