Answer: It increase in fitness and genetic diversity .
Step-by-step explanation:
Incomplete dominance : It is a type of intermediate inheritance in which one allele for a specific trait does not completely dominant its paired allele.
Example : Cross pollination between red snapdragon and white snapdragon dragon . And results of pollination (cross) is pink snapdragon .
Co -Dominance. It occurs when both allele of a genes lack dominant and recessive relationships are phenotypically observed to the same extent .
In the heterozygous state , each allele has a distinct phenotypic effect .
Example : ABO Blood group is the best example of Co -dominance .
