| crossing-over | exchange of genetic material between homologous chromosomes when they are closely paired during meiosis 1. |
| diploid | having two of each type of chromosomes. |
| egg | female gamete. |
| fertilization | union of two that produces a diploid zygote. |
| gamete | reproductive cell produced during meiosis that has the haploid number of chromosomes. |
| gametogenesis | development of haploid cells into gametes such as sperm and egg. |
| haploid | having only one chromosomes of each type. |
| independent assortment | independent segregation of chromosomes to gametes during meiosis. |
| life cycle | series of stages a sexually reproducing organism goes through from one generation to the next. |
| meiosis | type of cell division in which the number of chromosomes is reduced by half and four haploid cells result. |
| sexual reproduction | type of reproduction that involves the fertilization of gametes produced by two parents and produces genetically variable offspring. |
| sperm | male gamete. |
| zygote | diploid cell that forms when two haploid gametes unite during fertilization. |
