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.

Answer:
The 2 processes that occur in meiosis to create genetic diversity are <em>crossing over and independent assortment.</em> <em>Crossing over is when exchange of DNA segments occurs between homologous chromosomes. Independent assortment is when homologous chromosomes assort independently into gametes. </em>
Explanation:
Meiosis can be described as a process of cell division through which four daughter cells are produced having half the number of chromosomes as the parent cell.
During this process, the phenomenon of crossing over and independent assortment occurs which allows for the genetic diversity which we see in organisms of a species.
During Prophase 1 of meiosis 1, homologous chromosomes exchange segment of DNA between them which leads to genetic diversity.
During Anaphase 1 of meiosis 1, homologous chromosomes move to each side of the cell and the chances of the gamete to receive any of the chromosome is random.
