Question

The method of reproduction which generates a great deal of genetic diversity is

• A. Binary fission
• B. Sexual reproduction
• C. Asexual reproduction
• D. Alternation of generations
• E. Binary fission and conjugation

Answer 1

Answer: (B)

Sexual reproduction

Sexual reproduction involves fusion of the sex cells - the sperm and egg. This fusion leads to mixing of genes of 2 sex cells. The resultant offspring has a mixture of genes from both father and mother. This leads to more genetic variation. In asexual reproduction, there is no mixture of genes. Hence no genetic variation or diversity. Thus, the correct answer is option B.
