Answer 1

$\huge \rm {\underline{★Answer}}$

A meiocyte is the type of cell in the organism which differentiates into a gamete through the process of meiosis.

Generally, through meiosis, the diploid meiocyte divides into four genetically different haploid gametes.

So, the meiocytes are diploid cells i.e., 2N= 20.

Since a somatic cell is also a diploid cell. So, the somatic cell 2N= 20.

So, the correct answer is '- 20'.
