| Question | Answer |
|---|---|
| Adaptation | An inherited behavior or physical characteristic that helps an organism survive and reproduce in its environment. |
| Behavioral | Actions organisms take—instinctive or learned—to survive and reproduce in their environment |
| Structural | Structural adaptations are physical features of an organism like the bill on a bird or the fur on a bear |
| Physiological | Internal, automatic, and metabolic adjustments within an organism’s cells, tissues, or organs that improve survival in response to environmental stimuli (venom, toxins) |
| Chromosome | A threadlike structure within a cell’s nucleus that contains DNA that is passed from one generation to the next. |
| Dominant allele | An allele whose trait always shows up in the organism when the allele is present. |
| Gene | A sequence of DNA that determines a trait and is passed from parent to offspring. |
| Genetic trait | a specific, inheritable characteristic or feature of an organism (eye color, height, or blood type) encoded in DNA and passed from parents to offspring |
| Genome | A complete set of genetic information that an organism carries in its DNA. |
| Genotype | An organism’s genetic makeup, or allele combinations. |
| Heredity | The passing of traits from parents to offspring. |
| Inherited | The process by which genetic information, traits, and characteristics are passed from parents to their offspring through DNA during reproduction |
| Offspring | the new organism produced by living parents through sexual or asexual reproduction. |
| Phenotype | An organism’s physical appearance, or visible traits. (fur color, eye color, etc) |
| Recessive allele | An allele that is hidden whenever the dominant allele is present. |
| Reproduction | the fundamental biological process by which existing organisms (parents) produce new individual organisms (offspring), ensuring the continuation of a species |
| Asexual reproduction | A reproductive process that involves only one parent and produces offspring that are genetically identical to the parent. |
| Diverse offspring | offspring that are genetically unique, differing from both their parents and each other due to combined genetic material from sexual reproduction |
| Gene pool | the total collection of all genes, including their diverse alleles, present within a specific, interbreeding population of a species at a given time |
| Genetic diversity | the total variety of genes, alleles, and genetic traits within a species or population |
| Genetic variation | the diversity in gene sequences and DNA among individuals within a population or species, serving as the raw material for natural selection and evolution |
| Genetically identical | organisms or cells that possess the exact same DNA sequence and genetic makeup |
| Sexual reproduction | A reproductive process that involves two parents that combine their genetic material to produce a new organism which differs from both parents. |
| Uniform offspring | genetically identical clones of a single parent and each other, resulting from asexual reproduction |
