| genetic recombination | the product of crossing over - a new mixture of genetic material |
| oogenesis | the production of mature egg cells |
| independent assortment | during meiosis, the random distribution of genes from different chromosomes to the gametes |
| crossing over | the exchange of genes by reciprocal segments of homologous chromosomes during meiosis |
| polar body | one of two small cells produced and discarded during each of the two meiotic divisions that yield the haploid egg |
| gamete | a reproductive cell |
| spermatid | in meiosis, a haploid cell that develops into a mature sperm cell |
| synapsis | the pairing of homologous chromosomes during meiosis |
| spermatogenesis | the production of sperm cells |
| sexual reproduction | the production of offspring from the combination of genetic material from two parent organisms |
| asexual reproduction | the production of offspring that does not involve the union of gametes |
| tetrad | a group of two homologous chromosomes during meiosis |
