Question

select the statements that correctly describe the process of natural selection. the immediate change in allele frequency in a population over many generations brings about the evolution of individuals results in the adaptation of a population to its environment acts directly on specific alleles interacts with the phenotype of an organism

Answer 1

Natural selection describes the process by which advantageous alleles become more common in a population over many generations, leading to the adaptation of the population to its environment. It acts on the phenotype of organisms, affecting their survival and reproductive success.

Step-by-step explanation:

The correct statements that describe the process of natural selection are that it:

Results in the adaptation of a population to its environment through increased frequency of beneficial alleles and decreased frequency of deleterious alleles.

Acts on the phenotype of an organism, as natural selection can only increase or decrease the frequency of alleles within a population if those alleles affect the organism's phenotype in a way that impacts survival and reproduction.

Requires genetic variation in a population and operates over many generations, not causing the immediate change in allele frequency but rather a gradual change that can lead to evolution.

Answer 2

Natural selection acts on the population's heritable traits, selecting for beneficial alleles and adapting the population to the environment. It acts on entire organisms, not specific alleles, and interacts with the phenotype of an organism.

Step-by-step explanation:

Natural selection acts on the population's heritable traits: selecting for beneficial alleles that allow for environmental adaptation, and thus increasing their frequency in the population, while selecting against deleterious alleles and thereby decreasing their frequency. Natural selection acts on entire organisms, not on an individual allele within the organism. An individual may carry a very beneficial genotype with a resulting phenotype that, for example, increases the ability to reproduce (fecundity), but if that same individual also carries an allele that results in a fatal childhood disease, that fecundity phenotype will not pass to the next generation because the individual will not live to reach reproductive age.
