C Assortive Mating Is the answer
Recessive traits ;
The condition that is NOT applicable to the Hardy-Weinberg Equilibrium is assortative mating, which involves non-random mating based on phenotypic similarities. For a population to maintain Hardy-Weinberg Equilibrium, it must meet conditions such as large population size, no mutations, random mating, no natural selection, and no gene flow. Assortative mating violates the requirement of random mating, thus affecting allele frequencies.
