If a meiocite of maze has chormosome number 20 and the total DNA 20Pg.Find the chromosome number and the 'C' value in its endosperm cell in G2 phase

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 'Option C- 20'.
