An organism has 16 chromosomes in its skin cell. How many chromosomes are in its heart cells?
A
16
B
32
C
8
D
64
Explanation: 

Detailed explanation-1: -Thus, it will have 8 chromosomes in their cell. Hence, the correct answer to this question is option A. 8.

Detailed explanation-2: -This division is an important event since after fertilisation haploid chromosomes from each gamete (male and female) fuse to retain the diploid state in the zygote. Diploid means two sets of chromosome and haploid is one set. Since here the diploid set is 16 thus one set will be half it, i.e, 8.

Detailed explanation-3: -An organism has 16 chromosomes in diploid cells. The number of chromosomes present in the haploid cells produced by this organism will be 8. Haploid cells contain only one set of chromosomes i.e. half the number of chromosomes as are present in diploid cells. Gametes are haploid cells.

Detailed explanation-4: -So the final answer is 8 chromosomes.
