WebA dominant allele, that can originate from just one parent, causes a dominant phenotype in those who possess one copy of the gene. A person needs two copies of a recessive allele, one from each parent, in order for it to result in a recessive phenotype. A dominant and a recessive trait for a gene will result in a person with the dominant phenotype. WebFeb 7, 2024 · You can determine the genotypic ratio by counting the number of occurrences of each genotype. Based on the possible genotypes, you can assess the phenotypes. For example, if allele A is dominant and a is recessive: genotype AA will be expressed by phenotype A; genotype Aa will be expressed by phenotype A; and
WebDominant phenotypes are not always more common than recessive phenotypes.
