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.

Shortly after the zygote is formed, it begins the processes of duplication and division, each resulting new cell has the same number of chromosomes as was contained in the zygote. A fertilized egg is called a zygote until it divides into 16 cells, forming a ball-shaped structure called a morula. The events during the zygote stage involves integration of both parents' DNA into the cell nucleus and the beginning of rapid cell division, or cleavage.
Blood cells use a protein called hemoglobin to capture and carry oxygen.
