Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A guinea pig cell has 64 chromosomes. After mitosis, each daughter contains ____ chromosomes.
A
128
B
64
C
32
D
16
Explanation: 

Detailed explanation-1: -Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes. Each chromosome consists of 2 sister chromatids.

Detailed explanation-2: -Horse diploid cells contain 64 chromosomes (2n=64).

Detailed explanation-3: -When a diploid cell having 48 chromosomes divides, the four haploid daughter cells are produced at the end of meiosis II. Each daughter cell contains half of the chromosomes in number as that of the parent cell. Thus, it can be concluded that daughter cells produced from the parent cell will have 24 chromosomes.

Detailed explanation-4: -If a cell has 15 pairs of chromosomes (n = 15), it has 30 chromosomes (2n = 30). At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes.
