what does dominance mean in biology
In genetics, dominance pertains to the property of a gene (or allele) in relation to other genes or alleles. A gene or allele shows dominance when it suppresses the expression, or dominates the effects, of the recessive gene (or allele). There are many forms of dominance: complete dominance, incomplete dominance, and codominance. Codominance is a form of dominance wherein the alleles of a gene pair in a heterozygote are fully expressed.
