If a sperm cell has a chromosome number of n=10, which of the following statements is true?
A
The organism’s somatic cells will have a chromosome number of 2n=40
B
The organism’s somatic cells will have a chromosome number of n=10
C
The zygote will have a chromosome number of 2n=20
D
The organism’s gametes will have a chromosome number of 2n=20
Explanation: 

Detailed explanation-1: -A diploid cell contains 10 chromosomes (2n = 10).

Detailed explanation-2: -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).

Detailed explanation-3: -The diploid chromosome number is 10. So, the haploid chromosome number will be= 10/2= 5.

Detailed explanation-4: -Haploidy (n) refers to the state of having the half of the set of chromosomes as in a germ cell or a gamete. Triploidy (3n) is a rare chromosomal abnormality when there is an extra pair of the chromosome in their cells. Example: endosperm in plants. Therefore, 2n = 20 chromosomes. n = 10 chromosomes.
