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. Incomplete dominance is a form of intermediate inheritance in which one allele for a specific trait is not completely expressed over its paired allele. In Incomplete dominance no single allele is dominant and the offspring will be a mixture of both parents. The phenotype will show both traits of the parents in the offspring. In incomplete dominance, a heterozygous organism carrying two alleles wherein one is dominant and the other one is recessive, (Aa), the dominant allele will only be partially expressed. Hence, the heterozygous (Aa) will have an intermediate phenotype.

Is Incomplete Dominance possible in humans? If so, how do you know if it is incomplete dominance?
ReplyDeleteSo if I were to take a heterozygous white dog and cross it with a homozygous black dog, what would happen?
