WebIn this scenario, the alleles of a gene can either be dominant or recessive, which means that if a dominant allele is present, it will be expressed more than any recessive alleles that may be present in the genotype. If a recessive allele is present, it will be expressed less than the dominant allele. WebThis type of epistasis is sometimes called dominant suppression, because the deviation from 9:3:3:1 is caused by a single allele that produces a dominant phenotype, and the …
