Calculate the amount of DNA present in a pollen grain and the male gamete that is formed from the pollen mother cell with 20pg of DNA at G1 phase.

Question

Calculate the amount of DNA present in a pollen grain and the male gamete that is formed from the pollen mother cell with 20pg of DNA at G1 phase. (A) 40pg and 20pg (B) 20pg and 20pg (C) 20pg and 10pg (D) 10pg and10pg

G1 phase - PMC-20pg; G2 phase - PMC- 40pg Amount of DNA in a pollen grain formed from it (40/4)=10pg. Male gamete DNA content is equal to pollen grain (unicellular haploid) DNA content (.10pg.) .

Q. Calculate the amount of $D N A$ present in a pollen grain and the male gamete that is formed from the pollen mother cell with 20pg of $D N A$ at G₁ phase.

40pg and 20pg

20pg and 20pg

20pg and 10pg

10pg and10pg

G₁ phase - $PMC - 20 p g;$ G₂ phase - $PMC -$
$40 p g$
Amount of $D N A$ in a pollen grain formed from it $\frac{40}{4} = 10 p g .$ Male gamete $D N A$ content is equal to pollen grain (unicellular haploid) $D N A$ content $(10 p g)$ .
