How do you determine the genotype of a parent
WebDec 18, 2024 · If an individual inherits two identical alleles, their genotype is said to be … WebFirst of all, determine whether the condition is recessive or dominant. If the trait is dominant, the trait must be one of the parents'. If the phenotype is recessive, because they may be heterozygous, no parent is expected to have the phenotype. Then, determine whether an autosomal or sex-linked (usually X-linked) trait appears on the chart.

To construct a Punnett square, the genotypes of both parents must be known. One parent’s alleles are listed across the top of the table, and the other parent’s alleles are listed down the left hand side. The resulting offspring genotypes are produced at the intersection of the parent’s alleles.
