Final Answer:

False. because The color dilution gene in horses is not an example of incomplete dominance.

Step-by-step explanation:

Incomplete dominance refers to a genetic scenario where the heterozygous phenotype is an intermediate blend of the two homozygous phenotypes.

In the case of the color dilution gene in horses, it does not exhibit incomplete dominance. Instead, it demonstrates a different mode of inheritance known as a dilution gene, specifically the "d" or "cream" gene.

The color dilution gene in horses affects the intensity of coat colors by diluting the pigments. Horses with one copy of the dilution gene (heterozygous) exhibit a diluted coat color, while those with two copies (homozygous) may have an even more diluted color.

The interaction of this gene is not characterized by an intermediate phenotype in heterozygotes, which is the hallmark of incomplete dominance. Understanding the various modes of inheritance in genes affecting coat color in horses is essential for breeders and enthusiasts in maintaining and predicting desirable color patterns in horse populations.
