lf the pollen grain of a plant has 40 pg of DNA in its nucleus then how much DNA would a diploid cell of the same organism have in metaphase-I of meiosis ?

If the pollen grain of a plant has 40pg of DNA (c) in its nucleus then the amount of DNA in the diploid cell of the same organism in metaphase-I of meiosis would be 4c= 40x4=160pg of DNA.
