Answer:
C. Polygenic in which offspring receive three allele from each parent.
Explanation:
In genetics, a polygenic inheritance is an inheritance that involves more than one gene i.e. more than one gene controls a particular trait. This is the case of the skin color trait in humans, which is controlled by three genes.
However, since each gene contains two alleles, each parent will contribute three alleles for the three genes to the development of an offspring i.e. three alleles from the father and three from the mother will result in three genes in the offspring, each containing two alleles.
