Detailed explanation-1: -So to convert between haploid and diploid cells, we simply need to double the number of chromosomes. If a haploid cell of a koala has eight chromosomes, the number of chromosomes in a diploid cell from the same koala must be double this number. Therefore, a diploid cell of a koala will contain 16 chromosomes.
Detailed explanation-2: -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-3: -Diploid cells contain two complete sets (2n) of chromosomes. Haploid cells have half the number of chromosomes (n) as diploid-i.e. a haploid cell contains only one complete set of chromosomes. Diploid cells reproduce by mitosis making daughter cells that are exact replicas.
