Answer:
The alleles for red and white coat color are co-dominant.
Explanation:
Co-dominance is the condition when none of the allele of a gene is dominant. The heterozygous genotype exhibits traits of both alleles.
In the given example, the offspring have roan coat color in which white hairs are mixed into a base coat of red. Since both the alleles are expressed in heterozygous offspring, the alleles for red and white coat colors are co-dominant over each other.
The answer is concentration gradient. Have a good day.
