Question

Which of the following is true about meiotic divisions?

• A. Meiosis-I is reductional and meisois-II is equational
• B. Meiosis-I is equational and meiosis-II is reductional
• C. Both meiosis-I and meiosis-II are reductional
• D. Both meiosis-I and meiosis-II are equational

Answer 1

The correct option is A Meiosis-I is reductional and meisois-II is equational

Meiosis involves two distinct divisions, they are meiosis-I and meiosis- II. In meiosis-I, the division is reductional, while in meiosis-II, the division is equational. In reduction division, the chromosome number is reduced from diploid (46 chromosomes) to haploid (23 chromosomes). The second meiotic division is an equational division because it does not reduce chromosome numbers.
