Lostsunrise [7]

Answer:

option c is correct that is 32

Explanation:

meiosis occur in two phases in the first phase DNA replication occur and amount of DNA becomes doubled without any changes in the chromosomes number and two daughter cells( each 2n) are formed

now in stage 2 each daughter cell undergoes mitosis with the formation of two cells  each with half chromosomes (n)

now 2n =32

n=32/2=16

after meiosis stage 1 ........ two daughter cell each with 32 chromosomes  

stage 2.... each daughter cell form two grand daughter cell each with 16 chromosomes

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>
