Gene | One set of instructions for an inherited trait |
Heredity | The passing of genetic traits from parent to offspring |
Genotype | The entire genetic make up of an organism: also the combination of genes for one or more specific traits |

Allele | One of the alternative forms of a gene that governs a characteristic, such as hair color |
Chromosomes | In a Eukaryotic cell, one of the structures in the Nucleus that are made up of DNA and protein: in a prokaryotic cell the main ring of DNA |
Dominant Trait | A trait that will appear in the offspring if one of the parents contributes it. |
Sperm Cell | A male reproductive cell of animals and plants that can unite with an egg cell to form a new individual cell |
Egg Cell | A female reproductive cell of animals and plants that can unite with a sperm cell to form a new individual |
Reproduction | The process by which living things produce offspring |
Asexual | Formed by, characterized by, or being a process of reproduction that does not involve the combining of male and female germ cells |
