What is the definition of complete dominance?

Complete dominance is a form of dominance in heterozygous condition wherein the allele that is regarded as dominant completely masks the effect of the allele that is recessive. For instance, an individual carrying two alleles that are both dominant (e.g. AA), the trait that they represent will be expressed.

Thereof, which is an example of an incomplete dominance?

Examples of Incomplete Dominance. Pink roses are often the result of incomplete dominance. When red roses, which contain the dominant red allele, are mated with white roses, which is recessive, the offspring will be heterozygotes and will express a pink phenotype.

What is an example of simple dominance?

We get one chromosome from our mother and one from our father. Simple dominance occurs when an inherited trait is coded for by a single gene and that gene has two versions, or alleles: the dominant version and the recessive version. The dominant allele of the gene hides the presence of the recessive allele.

What does epistasis mean explain and give an example?

There is that one gene or allele masking the phenotypic expression of the other genes or alleles in the interaction. That gene or allele masking the effect is referred to as epistatic. In contrast, the other gene(s) or allele(s) being masked is/are referred to as hypostatic. Epistasis may be recessive or dominant.
