Question

why gamet are are haploid

Answer 1

Gametes are always haploid. Gametes should be haploid for maintaining the chromosome number of the species.This is achieved by meiosis the reduction division in germ cells.

I hope this answer will help you.

Answer 2

here is your answer -

In testes diploid spermatogonium cell divides through meosis and forms sperm. Due to meosis the number of chromosomes divides and forms haploid sets. That's why gametes are always Haploid.

let's talk about meiosis -
Meiosis is a reductional division in which number of chromosomes becomes half after completion of division.

Haploidy of gametes are necessary because if gametes will be diploid then the number of Chromosomes continues multiplying at every generation. that's why gametes should always be haploid.

hope it helps.
