Question

There would be no evolution if:

• A. The inheritance of acquired character did not take place
• B. Somatic variations are inheritable
• C. Genetic variations were not found among members of population
• D. Somatic variation would not transform into genetic variations

Answer 1

The correct option is C

Genetic variations were not found among members of population

The correct option is C:

Explanation of the correct option:

1. Evolution is the process of biological population heritable traits changing through generations.
2. These traits are the results of gene expression passed down from parents to offspring during reproduction.
3. If there are no genetic variations between the populations then, evolution will not occur.
4. Genetic variations are important because it forms the basis of heredity and contributes to the evolution of organisms.
5. Genetic variations occur due to gene interactions with the environment and various combinations of genetic material.

Explanation of the incorrect options:

Options A, B, and D:

Inheritance of acquired traits and somatic variations will not affect the evolution of a population.

Final answer: There would be no evolution if genetic variations were not found among members of the population.
