Gametes are individual DNA strands that all have a pair. In a human, the male has 23 in each sperm cell, and the woman has 23 in each egg cell.

When the sperm and egg cell combine, the gametes combine and form matching pairs (not genetically identical) and then a zygote forms. The gametes are what makes up the genetical information of the zygote, which will eventualy grow inot a newborn. These gametes confirm what gender the baby will be, what they will look like ect.

These gametes can also pass on disease - for example, a gamete with a mutation that causes down's syndrome.
