Q: Genetic equilibrium occurs when what process doesn't exist within the population?


Read this paragraph and choose the correct option from the provided answers:

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.

 Choices:

- movement

- reproduction

- variation

- evolution


A:
evolution
