Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How many cells are produced at the end of meiosis?
A
2 diploid cells
B
4 haploid cells
C
4 diploid cells
D
2 haploid cells
Explanation: 

Detailed explanation-1: -At the conclusion of meiosis, there are four haploid daughter cells that go on to develop into either sperm or egg cells.

Detailed explanation-2: -Therefore, meiosis results in four haploid genetically unique daughter cells, each with half the DNA of the parent cell (Figure below). In human cells, the parent cell has 46 chromosomes (23 pairs), so the cells produced by meiosis have 23 chromosomes. These cells will become gametes.

Detailed explanation-3: -The nuclei re-form, and new nuclear membranes develop. This process results in four new cells, or gametes. Each gamete contains only one chromosome from each homologous pair. This makes the cell haploid, meaning that it has half the chromosome number of the original diploid cell.
