After meiosis, how many chromosomes does each cell have compared to the original cell?
A
double
B
equal
C
half
D
impossible to tell
Explanation: 

Detailed explanation-1: -Each daughter cell is haploid and has only one set of chromosomes, or half the total number of chromosomes of the original cell. Meiosis II is a mitotic division of each of the haploid cells produced in meiosis I.

Detailed explanation-2: -The number of chromosomes in human cells are 46. i.e, these are present in pairs of 23. These pairs break apart and get separated in meiosis I. Thus, each of the two daughter cells formed after first meiotic division have half the number of chromosomes, i.e., 23.

Detailed explanation-3: -Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.
