Question

Which set of statements accurately reflects the processes of genetic variation, the generation of new genetic combinations, and the preservation of successful genetic combinations in a particular environment?

a) 1. Mutation, 2. Substitution, 3. Evolution
b) 1. Mutation, 2. Recombination, 3. Natural selection
c) 1. Recombination, 2. Mutation, 3. Evolution
d) 1. Evolution, 2. Mutation, 3. Natural selection

Answer 1

The correct answer is b) 1. Mutation, 2. Recombination, 3. Natural selection, which describes processes that lead to genetic variation, the creation of new gene combinations, and the preservation of advantageous gene combinations.

Step-by-step explanation:

The set of statements that accurately reflects the processes of genetic variation, the generation of new genetic combinations, and the preservation of successful genetic combinations in a particular environment is given by: 1. Mutation, 2. Recombination, 3. Natural selection. Therefore, the correct answer is b) 1. Mutation, 2. Recombination, 3. Natural selection.

Mutations are changes to the genetic material (DNA or RNA) of an organism and can occur naturally or be induced by environmental factors. Mutations can introduce new genetic variations into a population. Recombination is a process by which pieces of DNA are broken and recombined to produce new combinations of alleles, which creates genetic diversity within a population. Natural selection is the mechanism by which certain genetic combinations increase an organism's chances of survival and reproduction, leading those traits to become more common in the population over time.
