WebFeb 7, 2024 · To find possible genotypes locate different combinations of alleles - AA, Aa, or aa. 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; WebDec 18, 2024 · An individual’s genotype is the combination of alleles that they possess for a specific gene.
