Answer the following question given this paragraph: The Hardy-Weinberg model describes how a population can remain at genetic equilibrium , referred to as the Hardy-Weinberg equilibrium. Genetic equilibrium occurs when there is no evolution within the population. In other words, the frequency of alleles (variants of a gene) will be the same from one generation to another. At genetic equilibrium, the gene or allele frequencies are stable they do not change. For example, let's assume that red hair is determined by the inheritance of a gene with two alleles R and r . The dominant allele, R , encodes for non-red hair, while the recessive allele, r , encodes for red hair. If a population's gene pool contains 90% R and 10% r alleles, then the next generation would also have 90% R and 10% r alleles. However, this only works under a strict set of conditions. Q: Genetic equilibrium occurs when what process doesn't exist within the population? Choices: - movement - reproduction - variation - evolution A:
Answer:
evolution
