Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Meiosis produces four cells with how many chromosomes in them?
A
46
B
41
C
38
D
23
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -In meiosis, a cell containing the diploid number of chromosomes is converted into four cells, each having the haploid number of chromosomes. In human cells undergoing meiosis, for instance, a cell containing 46 chromosomes yields four cells, each with 23 chromosomes.

Detailed explanation-3: -Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.

Detailed explanation-4: -This type of cell division is called mitosis, and it produces cells with a total of 46 chromosomes. Beginning soon after fertilization (see below), all of the cells in your body were made this way.

Detailed explanation-5: -Normally, each cell in the human body has 23 pairs of chromosomes (46 total chromosomes). Half come from the mother; the other half come from the father. Two of the chromosomes (the X and the Y chromosome) determine your sex as male or female when you are born.
