Detailed explanation-1: -If the egg cell has 10 chromosomes (haploid ‘n’), then the number of chromosomes present in diploid cell (2n) is 20. The mitotic cell division is also known as equational division meaning that the number of chromosomes in each daughter cell is the same as the number of chromosomes present in the parent cell.

Detailed explanation-2: -Explanation: Haploid means half, and diploid means double of the half, and so its diploid number will be 20⋅2=40 if its haploid number is 20 .

Detailed explanation-3: -Corn has diploid number of chromosomes. It is thus given as 2n = 20.

Detailed explanation-4: -Answer and Explanation: If an organism has a diploid number of 10 it has 10 chromosomes-5 homologous pairs. It will therefore 20 chromatids, all of which will be present in prophase.

Detailed explanation-5: -Humans have 46 chromosomes in each diploid cell. Among those, there are two sex-determining chromosomes, and 22 pairs of autosomal, or non-sex, chromosomes. The total number of chromosomes in diploid cells is described as 2n, which is twice the number of chromosomes in a haploid cell (n).
