During meiosis, the ____ daughter cells have ____ the number of chromosomes compared to the parent cells.
A
2, exact
B
four, 1/2
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes. Each chromosome consists of 2 sister chromatids. The daughter cells now move in to the third and final phase of meiosis: meiosis II. At the end of meiosis I there are two haploid cells.

Detailed explanation-3: -The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell. Meiosis has both similarities to and differences from mitosis, which is a cell division process in which a parent cell produces two identical daughter cells.

Detailed explanation-4: -After meiosis II, when each parent cell gets divided into two gametes each gamete cell contains 23 chromosomes. In this phase, each gamete remains haploid in nature. At the end of meiosis II, each cell will have the half number of the actual chromosome i.e. 23 chromosomes.

Detailed explanation-5: -So, the daughter cells formed during mitosis have the same number of chromosomes as the mother and are also identical to the parent cell. During meiosis four haploid daughter cells are produced, each having half the number of chromosomes as that of the mother cell.
