The fact that people with red hair usually have freckles is an illustration of A) independent assortment B) dominance C) intermediate inheritance D) gene linkage

D

Explanation:

The fact that people with red hair usually have freckles is an illustration of gene linkage.

Gene linkage is the tendency of 2 or more genes to be linked on the same chromosome and as such, inherited together during meiosis sexual reproduction. This is as opposed to independent assortment of genes which is the tendency of genes to be independently inherited during sexual reproduction/meiosis.

Linked genes are usually close to one another on the same chromosome and one cannot be independent of the other while independently assorting genes are usually far apart or even located on different chromosomes and are separately inherited.

The correct option is D.
