Question

If a horse inherits white hair (fur) genes from one parent and red hair (fur) resulting in a roan coat (fur), where you see both red and white hairs in the coat. This is _

Answer 1

CODOMINANCE

Step-by-step explanation:

Some patterns of inheritance that goes against Mendel's principles have surfaced. One of this so called Non-mendelian inheritance is CODOMINANCE. Co-dominance is a genetic scenario in which the alleles of a gene are neither dominant nor recessive over one another, hence, they are both simultaneously expressed in the hybrid phenotype.

This is the case here involving a gene coding for fur colour in horse. One of the alleles code for red hair while the other allele for white hairs. Both alleles are said to be co-dominant because no one is dominant over the other, hence, they produce an hybrid phenotype called Roan where both red and hair phenotypes are seen/expressed.
