Question

Which of the following is the cause of speciation?

• A. Point mutation
• B. Gross mutation
• C. Both A and B
• D. None of the above

Answer 1

The correct option is C Both A and B

Point mutation is a type of mutation that causes a single nucleotide base change, insertion, or deletion of the genetic material, DNA or RNA.

Gross mutations also known as Chromosomal mutations are the mutations that alter the structure of the individual chromosome. Both Point mutation and gross mutation is the cause of speciation which is the evolutionary process by which reproductively isolated biological populations evolve to become distinct species. Thus, the correct answer is option D.
