| Meiosis | a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores. |
| chromosome | a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes. |
| gamete | a mature haploid male or female germ cell that is able to unite with another of the opposite sex in sexual reproduction to form a zygote. |
| zygote | a diploid cell resulting from the fusion of two haploid gametes; a fertilized ovum. |
| diploid | of a cell or nucleus) containing two complete sets of chromosomes, one from each parent. |

| ovum | a mature female reproductive cell, especially of a human or other animal, that can divide to give rise to an embryo usually only after fertilization by a male cell. |
