If stem has 2 n=10 number of chromosomes then find out A - number of chromosome in endosperm. B - number of chromosome in egg cell. C - number of chromosome in polar nuclei, respectively.

Question

If stem has 2 n=10 number of chromosomes then find out A - number of chromosome in endosperm. B - number of chromosome in egg cell. C - number of chromosome in polar nuclei, respectively. (A) 15,15,20 (B) 10,15,20 (C) 15,5, 10 (D) 10,5, 15

If stem has 2 n=10 number of chromosomes, then Endosperm =3 n=5 × 3=15 chromosomes. Egg cell =1 n=1 × 5=5 chromosomes. Polar nuclei =2 n=2 × 5=10 chromosomes.

Q. If stem has $2 n = 10$ number of chromosomes then find out
$A$ - number of chromosome in endosperm.
$B$ - number of chromosome in egg cell.
$C$ - number of chromosome in polar nuclei, respectively.

15,15,20

10,15,20

15,5, 10

10,5, 15

If stem has $2 n = 10$ number of chromosomes, then
Endosperm $= 3 n = 5 \times 3 = 15$ chromosomes.
Egg cell $= 1 n = 1 \times 5 = 5$ chromosomes.
Polar nuclei $= 2 n = 2 \times 5 = 10$ chromosomes.
