All of their offspring have a phenotype of gray coats, the most likely pattern of inheritance for coat color in sheep is Incomplete dominance.
What does it mean to have a dominant gene?
Dominant genes are those that determine a hereditary trait even when in single dose in the genotype. That is, they determine its character even in the absence of its dominant allele.
Skin color is determined by a series of genes. To better understand the polygenic inheritance of skin color, we will consider three genes: A, B and C. These genes contribute in a way to make the skin darker and have incomplete dominance over a, b and c.
