Detailed explanation-1: -so an animal with a diploid number of chromosomes equal to 30 will produce four gametes. Each gamete will contain 15 chromosomes due to meiosis.

Detailed explanation-2: -If a cell has 15 pairs of chromosomes (n = 15), it has 30 chromosomes (2n = 30). At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes.

Detailed explanation-3: -so an animal with a diploid number of chromosomes equal to 30 will produce four gametes. Each gamete will contain 15 chromosomes due to meiosis. Thus option D is the correct answer.

Detailed explanation-4: -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.
