Question

Which of the following statements best describes the role of genetics in natural selection? Which of the following statements best describes the role of genetics in natural selection? Genetic mutations directly determine environmental changes. Natural selection operates independently of genetic variations. Environmental factors have no impact on genetic variations. Natural selection acts on the genotype, influencing the expression of genes.

Answer 1

Natural selection acts on the genotype, influencing the expression of genes. It selects for beneficial traits and works to increase their frequency in the population.

Step-by-step explanation:

Natural selection acts on the genotype, influencing the expression of genes. Genetic mutations introduce new variation into a population, which can be subject to natural selection. Natural selection selects for alleles that confer beneficial traits or behaviors and against those with deleterious qualities. It acts on the population's heritable traits, not on individual alleles, and works to increase the frequency of beneficial alleles in the population.
