Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The daughter cells (gametes) have ____ DNA compared to the parent cell after meiosis.
A
the same
B
half as much
C
double
D
identical
Explanation: 

Detailed explanation-1: -Final answer: After meiosis I, the resultant daughter cells have twice the amount of DNA in comparison to haploid gamete.

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: -Genetic variation in daughter cells Daughter cells are genetically identical with each cell and with the parent cell.

Detailed explanation-4: -At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes.

Detailed explanation-5: -After meiosis I, DNA content gets equally divided into the two cells which means each cell is 30pg. Both the cells undergo further division to form 4 haploid cells during the process of meiosis II. That means the content is further reduced to half i.e 15 pg DNA in each cell(M II).
