| The body cells of animals are | diploid. |
| ______ cells have one complete set of chromosomes. | Haploid |
| In animals, gametes (sperm and eggs) are | haploid. |
| _________ chromosomes are two chromosomes that are the same | Homologous |
| ______ organisms have two of each chromosome | diploid |
| In a diploid, Each of the pairs is a ____ pair | homologous |
