Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The four gametes produced in meiosis contain ____ DNA
A
Identical
B
Unique
C
Either A or B
D
None of the above
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: -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-3: -Like your genome, each gamete is unique, which explains why siblings from the same parents do not look the same. Following fusion of the egg and sperm, another type of cell division called mitosis occurs, producing two identical cells from one.

Detailed explanation-4: -We produce gametes by meiotic cell division. We reduce the number of chromosomes to one half. And not just any half. Each of the four cells produced by meiosis has all of the 23 chromosomes, half a set of homologous pairs.

Detailed explanation-5: -At the conclusion of meiosis, there are four haploid daughter cells that go on to develop into either sperm or egg cells.
