Question

What will be the ploidy of endosperm and zygote if the cross is made between a 6n female plant and a 4n male plant?

Answer 1

Ploidy of endosperm and zygote if the cross is made between a 6n female plant and a 4n male plant, Endosperm is formed by the fusion of polar nuclei and male gamete.

: Ploidy level of male plant is 4N

:Male gamete = 2N

:Endosperm = 2 polar nuclei + 1 male gamete

:(3N + 3N) + 2N

So the end result is 8N.
