Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The diploid number is 90, so that means the haploid number is
A
90
B
180
C
45
D
60
Explanation: 

Detailed explanation-1: -The total number of chromosomes in diploid cells is described as 2n, which is twice the number of chromosomes in a haploid cell (n).

Detailed explanation-2: -Humans, like many other species, are called ‘diploid’. This is because our chromosomes exist in matching pairs – with one chromosome of each pair being inherited from each biological parent. Every cell in the human body contains 23 pairs of such chromosomes; our diploid number is therefore 46, our ‘haploid’ number 23.

Detailed explanation-3: -If a diploid cell contains 40 chromosomes, then the haploid cell contains 20 number of chromosomes. The haploid cells contain half the number of chromosomes as the diploid cells. Thus, if a diploid cell contains 40 chromosomes, then the haploid cell will contain 20 chromosomes.

Detailed explanation-4: -Glossary of ploidy numbers The haploid number (half of 48) is 24.
