So that two haploid gametes (1 egg and 1 sperm) make a diploid embryo, with two sets of chromosomes (a maternal and paternal set). When this happens, you get a genetically unique offspring with a full set of chromosomes.

Gametes have to be haploid because it has 2 (di- means 2) chromosomes, one from mom and one from dad. If gametes only have one chromosme, it would be called haploid, a structure contains only 1 chromosome.
Gametes also carry genetic info. from parents (parents equal 2 individuals) passing out to their offspring because the info. is mixed from 2 parents.

Think about it. If you had an egg and sperm with a full 46 in each, and you put them together to make a baby, that baby would have 92 chromosomes. So, to keep the number of chromosomes constant, haploid is the way to go.

so when the gamete joins with another gamete of the opposite sex that zygjote will become a diploid. if they were diploid and they joined together there would be too many chromosomes.

If they weren't we'd have twice the amount of chromosomes we are supposed to...

so that you don't end up with 92 chromosomes!

for the chromosomes constancy
