| 8848800385 | autosomes | a chromosome that is not directly involved in determining sex; non sex chromosome | 12 | |
| 8848804911 | diploid | a cell with two sets (paired) chromosomes; 2n somatic cells | 13 | |
| 8848814675 | haploid | a cell that contains a single set of chromosomes; 1n; gametes | 14 | |
| 8848817715 | fertilization | union of gametes | 15 | |
| 8848820824 | zygote | fertilized egg resulting from fertilization | 16 | |
| 8848824649 | meiosis | gamete formation; consists of two rounds of cell division to reduce chromosome number in half; results in 4 genetically different daughter cells | 17 | |
| 8848838570 | meiosis I | first division of a two-stage process of cell division in sexually reproducing organisms that results in cells with half the number of chromosome sets as the original cell | 18 | |
| 8848844568 | meiosis II | second division of a two-stage process of cell division in sexually reproducing organisms that results in cells with half the number of chromosomes as the original cell | 19 | |
