dominance in that neither allele is recessive or masked; instead, both are expressed simultaneously. This results in unique phenotypic traits that reflect the presence of both alleles. Characteristics of Codominance Both alleles contribute equally to the phenotype. The heterozygote
Carriers: Aa Affected: aa Step 5: Conclude that the trait is autosomal recessive because: It appears in both sexes equally. It can skip generations. Affected individuals often have carrier parents. Visual Aids: Pedigree chart with affected individuals marked, wi
