A cell under a microscope shows Two daughter cells were formed and they are haploid. Which stage of meiosis is the cell showing?
Nadya [2.5K]

The answer is <span>Meiosis I.</span>



<span>Meiosis is a cell division which results in the reduction of chromosome number by half - from diploid to haploid - in daughter cells. It consists of meiosis I and meiosis II. Meiosis I produces two haploid cells. Meiosis II is analogous to mitosis, so each of these two haploid cells will in meiosis II produce two haploid cells. In total, meiosis results in four haploid cells.</span>

<span>
</span>

<span>Therefore, the production of two haploid daughter cells is in meiosis I.</span>
