Inherited Traits
| Term | Definition |
|---|---|
| Adaptation | A trait that helps an organism survive and reproduce in its environment. |
| Artificial selection | The process by which humans breed plants and animals for desired traits. |
| Asexual reproduction | A type of reproduction involving only one parent, resulting in offspring that are genetically identical to the parent. |
| Mutation | A change in an organism’s DNA that can lead to variations in traits. |
| Natural selection | A process in which organisms with beneficial traits survive and reproduce more successfully, leading to changes in the population over time. |
| Sexual reproduction | A type of reproduction that involves two parents and produces genetically diverse offspring. |
| Traits | A characteristic or feature of an organism, such as eye color or leaf shape. |
| Genetic Diversity | Variations in genetic information among individuals of a population, which increases the chances of survival in a changing environment. |
| Generation | a succession of birth cohorts; it is essentially the average period during which offspring are born, develop and mature, and then have offspring of their own. |
| Offspring | he young creation of living organisms, produced either by a single organism or, in the case of sexual reproduction, two organisms. |
| Organism | A living thing, such as a plant, animal, or microorganism. |
| Environment | The surroundings in which an organism lives, including both living (biotic) and nonliving (abiotic) factors. |
| Reproduction | The biological process by which new organisms are produced. |
| Heredity | The passing of genetic traits from parents to offspring. |
| Gene | A section of DNA that carries instructions for a specific trait. |
| Chromosome | A structure within cells that contains DNA and genes. |
| DNA (Deoxyribonucleic Acid) | The molecule that carries genetic instructions in living organisms. |
| Variation | Differences in traits among individuals in a population. |
| Survival of the Fittest | The idea that individuals with the most advantageous traits are more likely to survive and pass on their genes. |
| Evolution | The gradual change in a species over time due to natural selection and genetic variation. |
| Population | A group of organisms of the same species living in a particular area. |
| Species | A group of organisms that can interbreed and produce fertile offspring. |
| Biodiversity | The variety of living organisms in an ecosystem, important for stability and resilience. |
| Cloning | The process of making an identical genetic copy of an organism. |
| Hybrid | The offspring of two different species or varieties with mixed traits. |
