Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A make believe organism has 10 chromosomes for each of its body cells. Cells are continuously being rubbed off and replaced. The mature eggs of this female would contain how many chromosomes?

A	5
B	10
C	20
D	30

Explanation:

Detailed explanation-1: -So, the haploid chromosome number will be= 10/2= 5. The number of possible chromosome pairs is given by= 2n, where n is the haploid chromosome number. So, the number of chromosome pairs for having a diploid chromosome number of 10 will be= 25. So, the correct answer is ‘25’.

Detailed explanation-2: -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-3: -Correct answer is option b) 20. Explanation: If the egg cell has 10 chromosomes (haploid ‘n’), then the number of chromosomes present in diploid cell (2n) is 20.

Detailed explanation-4: -Answer and Explanation: If a cell containing 10 chromosomes divides by mitosis two daughter cells will be produced. Mitosis is the process of cell division and creates two identical daughter cells from one parent cell.
