Solution
The correct option is D 8 x
An octaploid male plant will have tetraploid (4x) male gamete. For a 4x female, haploid number is 2x. In it's embryo sac, the two polar nuclei (2x, 2x) will fuse with the male gamete (4n) and form an 8x endospermSo, the correct answer is '8 x'
An octaploid male plant will have tetraploid (4x) male gamete. For a 4x female, haploid number is 2x. In it's embryo sac, the two polar nuclei (2x, 2x) will fuse with the male gamete (4n) and form an 8x endosperm
So, the correct answer is '8 x'
