Detailed explanation-1: -The total number of chromosomes is referred to as the chromosome number. The haploid number in humans is given as 2n=46, n = 23, this is because the haploid human cells possess one set of 23 chromosomes – 22 sets of autosomal chromosomes (non-sex chromosomes) and 1 set of sex chromosomes.

Detailed explanation-2: -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-3: -Since haploid cells have half the number of chromosomes than diploids, the haploid number of chromosomes for a cell whose diploid counterpart has a diploid number of 12 would be 6 (12/2=6).
