How do gametes enable humans to reproduce?

Gametes have adaptations to increase the chances of fertilisation and successful development of an embryo. For example, sperm cells are produced in large numbers to increase the chance of fertilisation. Sperm cells have these adaptations: a tail to move them towards an egg cell.

GAMETES in the study of cells can be defined as a reproductive cell (sperm in males or eggs in females), having only half of a complete set of chromosomes. Gametes enable humans to produce when a haploid cell (having a single set of unpaired chromosomes) fuses with another haploid cell during fertilization.

Sperm cells are produced in large numbers to increase the chance of fertilisation.
