Question

When a diploid female plant is crossed with a tetraploid male,the ploidy of endosperm cells in the resulting seed is?

Answer 1

Explanation:

The male makes 2n gametes. The female makes 1n gametes. Two male sperm cells and one central cell from the female are combined in the formation of the endosperm.

2n + 2n + 1n gives 5n for the endosperm

Answer 2

Answer:

the diploid female produces embryo sac in which egg cell has n and polar nuclei have 2n (due to the presence of two nuclei) and tetraploid male (4n) .
