Question

Why is freckles not X linked dominant trait

Answer 1

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.

The melanocortin receptor gene 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.

Under no circumstances is the transmission of the gene that determines the presence of freckles linked to sex, because is an autosomal trait, as is hair, eye or skin color.
