Question

Read the following statements and select the correct option.
A. Genetic diversity within a species often decreases with environmental variability.
B. Genetic diversity plays a key role in the process to speciation.

• A. Only (A) is correct
• B. Only (B) is correct
• C. Both (A) and (B) are correct
• D. Both (A) and (B) are incorrect

Answer 1

Answer: (B)

Environmental heterogenicity increases with genetic diversity. Genetic diversity causes more variety of species to exist in the same geographical area resulting in speciation. The diversity serves as an adaptation of populations to environmental changes. Genetic drift influences the diversity of the organisms and this is the basis of evolution.
