Answer :
Codominance. The dominance in which the two alleles or traits of the genotypes (of both homozygotes) are displayed simultaneously in offspring is referred to as codominance (phenotype). In cross-breeding, neither a dominant nor a recessive allele exists.
How do genes and alleles relate to one another?
A gene is a segment of DNA or RNA that controls a certain trait. Genes are subject to mutation and can exist in two or more distinct forms; an allele is one of these forms.
Is the ABO blood types' manner of inheritance indicative of dominance? Is there codominance or regression?
Inheritance of the ABO blood type is autosomal dominant. The O allele is recessive and the codominant alleles are A and B.
