Why are gametes haploid cells?

Mammals cannot survive as a haploid cell, and meiosis creates four gametes that are haploid, so the two haploid cells need to combine in order to have a diploid zygote that is also genetically different.

Because they contain only a single copy of either a mothers DNA or a fathers DNA. Most cells in the body with a nucleus contain 46 chromosomes that make up their DNA, a gamete is an exception because it contains 23 chromosomes, when a sperm (containing 23 chromosomes) fuses with an egg (containing 23 chromosomes) a zygote is formed which will develop into blastocyst and then onto a foetus. This zygote contains 46 chromosomes, enough genetic information to develop into a healthy baby.

Gametes, sex cells, are haploid because they make diploid zygotes. In sexual reproducing species, meiosis, the halving of chromosome number along sexual lines, male and female. is necessary so that when the sperm and egg meet in fertilization a proper chromosome number is maintained.
