Detailed explanation-1: -A cell with 10 chromosomes undergoes mitosis. The number of chromosomes that each of the new cells will have is c. 10 chromosomes each. Mitotic division results in two daughter cells with an identical chromosomal number and genetic content to the parental cell.
Detailed explanation-2: -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-3: -So, the correct option is ‘20’.
Detailed explanation-4: -Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 10, one copy inherited from each parent, form one of the pairs.
Detailed explanation-5: -For a cell with a diploid number of 10 (2n = 10), the two daughter cells that are produced after mitosis will contain ten chromosomes (identical to the parental cell).
