: The fusion of these two distinct cells ensures genetic diversity in the resulting offspring.
: Gametes are formed through meiosis , a two-part cell division process that reduces the chromosome count by half. Types : gamete
A is a specialized reproductive cell that carries a single set of chromosomes ( haploid ) and is used in sexual reproduction to form a new organism. When two gametes fuse during fertilization, they create a diploid cell known as a zygote , restoring the full number of chromosomes. Core Biological Function : The fusion of these two distinct cells
: Larger, immobile, and contains the cytoplasm and nutrients needed for early development. When two gametes fuse during fertilization, they create
: Typically small, highly motile, and produced in large quantities within the testes (animals) or anthers (plants).
