Question

Species-specific chromosome number is maintained generation after generation by

• A. Mitosis
• B. Meiosis
• C. Amitosis
• D. None of the above

Answer 1

Answer: (B)

Meiosis

Species-specific chromosome number is maintained generation after generation by meiosis. The meiosis is a kind of reductive division. When gametes are formed by meiosis, the number of chromosomes is halved. Hence each gamete will have only one pair of chromosome. Later the haploid gamete will fuse with the complementary haploid gamete and form a diploid zygote (2n). Hence the number of chromosomes are maintained.

So, the correct answer is 'Meiosis'.
