| Term | Definition |
|---|---|
| characteristics | a feature or quality belonging typically to a person, place, or thing and serving to identify it. |
| gene | a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring. |
| genetics | the study of heredity and the variation of inherited characteristics. |
| inherited trait | a trait that a person gets from a parent or grandparent |
| acquired trait | characteristics that are gained by an organism after birth as a result of external influences or its own activities that change its structure or function and cannot be inherited |
| trait | a distinguishing quality or characteristic, typically one belonging to a person. |
| asexual reproduction | a type of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only; it does not involve the fusion of gametes and almost never changes the number of chromosomes |
| cell | the smallest structural and functional unit of an organism |
| clone | an organism or cell, or group of organisms or cells, produced asexually from one ancestor or stock, to which they are genetically identical |
| mutation | the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations |
| sexual reproduction | the production of new living organisms by combining genetic information from two individuals of different types (sexes) |
| allele | one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome |
| dominant | most important, powerful, or influential |
| recessive | relating to or denoting heritable characteristics controlled by genes that are expressed in offspring only when inherited from both parents |
| homozygous | if you're homozygous, you've got a pair of matching alleles, which are the two genes that control a particular trait |
| heterozygous | the genetics term heterozygous refers to a pair of genes where one is dominant and one is recessive — they're different |
| phenotype | the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment |
| Punnett square | a diagram that is used to predict an outcome of a particular cross or breeding experiment |
| genotype | the genetic constitution of an individual organism |
