Question

Minimum number of meiotic divisions required to produce 1000 male gametes in a flowering plant is

Answer 1

In angiosperms, 1 meiotic division of Megaspore mother cell leads to formation of one egg cell.

So xx egg cells are formed from xx number of meiotic division.


But 1 meiotic division of Sperm mother cell (2n) leads to formation off 4 haploid cells (male gametes).

So by Unitary method,

4 functional male gametes are formed from 1 Meiotic division

xx functional male gametes are formed from 1/4 x xx Meiotic divisions


So total number of meiosis needed to produce xx seeds = xx + xx/4.

Answer 2

Hola mate !!

here's your answer...

One meiotic division in flowering plants produce 4 male gametes .

Therefore ,
