| Question | Answer |
|---|---|
| cell that makes up all of the body tissues and organs, except gametes | somatic cell |
| sex cell, an egg or a sperm cell | gamete |
| chromosomes that have the same length, appearance, and copies of genes, although the alleles may differ | homologous chromosomes |
| chromosome that contains genes for characteristics not directly related to the sex of the organism | autosome |
| chromosome that directly controls the development of sexual characteristics | sex chromosome |
| process by which two gametes fuse and offspring that are a genetic mixture of both parents are produced | sexual reproduction |
| fusion of an egg and sperm cell | fertilization |
| cell that has two copies of each chromosome, one from and egg and one from a sperm | diploid |
| cell that has only one copy of each chromosome | haploid |
| form of nuclear division that divides a diploid cell into haploid cells, important in forming gametes for sexual reproduction | meiosis |
| process by which gametes are produced through the combination of meiosis and other maturational changes | gametogenesis |
| male gamete | sperm |
| female gamete | egg |
| haploid cell produced during meiosis in the female of many species; these cells have little more DNA and eventually disintegrate | polar body |
