Question

Gametes are always haploid .how are the gametes produced from a haploid plant body and a diploid plant body?

Answer 1

When a wheat cell perform meiosis (producing micro and mega spores, and later on gametes), it produces haploid cells which are triploid. Wheat gametes are haploid and triploid. The same whay, a tetraploid organism would produce, by meiosis, a cell which is haploid and diploid.

Answer 2

Gametes are always haploid because -

1. In a haploid organism, gametes are produced by the process of MITOSIS which is also known as EQUATIONAL DIVISION as is the chromosome number remains the same.

2. In a diploid organism the gametes are produced by the process of MEIOSIS or REDUCTIONAL DIVISION, in which the chromosome number is reduced to half, that us from "2n" number of chromosome to "n" number of chromosome.
