Natural selection influences the frequency of an adaptation in a population.
B
Natural selection has been discarded as an unimportant concept.
C
New mutations of genetic material are caused by natural selection.
D
Changes in gene frequencies caused by natural selection have little effect on gradual genetic changes in species.
Explanation: 

Detailed explanation-1: -So, the correct answer is ‘Individuals with the most favorable traits survive and reproduce’

Detailed explanation-2: -So, the correct answer is ‘Individuals with the most favorable traits survive and reproduce’

Detailed explanation-3: -Natural selection allows adaptation in a population by selecting only beneficial alleles. It increases the allele frequencies of heritable traits. The natural selection process decreases deleterious alleles by selecting against them, leading to adaptive evolution.

Detailed explanation-4: -Natural selection is the process by which organisms develop variation in traits, which gives them a better chance of survival.

Detailed explanation-5: -Answer and Explanation: The correct option is-e-It is the different survival and reproduction of the most fit phenotypes.
