In the context of "The Complete Mendelian Genetics & Inheritance Course 2026," which of the following scenarios most accurately reflects a deviation from strict Mendelian inheritance that a "Genetics & Evolution Mastery Hub" student would be expected to analyze?
A student studying "The Complete Mendelian Genetics & Inheritance Course 2026" encounters a population exhibiting Hardy-Weinberg equilibrium for a specific gene. If the allele frequency for the dominant allele 'A' is 0.6, what is the expected genotype frequency of the heterozygous genotype 'Aa' in this population?
tests the practical application of Hardy-Weinberg principles. For a population in Hardy-Weinberg equilibrium, the genotype frequencies are p² (homozygous dominant), 2pq (heterozygous), and q² (homozygous recessive), where p and q are the allele frequencies of the dominant and recessive alleles, respectively. Given the frequency of the dominant allele 'A' (p) is 0.6, the frequency of the recessive allele 'a' (q) is 1 - p = 1 - 0.6 = 0.4. The expected genotype frequency of the heterozygous genotype 'Aa' is therefore 2pq = 2 * (0.6) * (0.4) = 0.48. Option B (0.36) represents p², the frequency of the homozygous dominant genotype. Option C (0.16) represents q², the frequency of the homozygous recessive genotype. Option D (0.24) is incorrect and does not correspond to any of the Hardy-Weinberg genotype frequency calculations. Question: Within the scope of "The Complete Mendelian Genetics & Inheritance Course 2026," consider a trait controlled by a gene with multiple alleles, where the order of dominance is A1 > A2 > A3. If an individual is heterozygous for the first two alleles (A1A2), what phenotype would they express, and what is the underlying genetic principle at play?
