In meiosis, division is
Options
- AI reductional and II equational
- BI equational and II reductional
- CBoth reductional
- DBoth equational
Correct answer
A. I reductional and II equational
Step-by-step solution
Meiotic division occurs in two stages, meiosis I and meiosis II, dividing the cells once at each stage. Meiosis I separates homologous chromosomes, producing two haploid cells ( N chromosomes , 23 in humans), and thus meiosis I is referred to as a reductional division . In meiosis II, an equational division similar to mitosis will occur whereby the sister chromatids are finally split, creating a total of 4 haploid cells ( 23 chromosomes , N) - two from each daughter cell from the first division.
