Genetics Vocab
| Question | Answer |
|---|---|
| Two forms of a gene (dominant or recessive) | Alleles |
| Piece of DNA that codes of a trait, basic physical and functional unit of heredity | Gene |
| Any characteristic that can be passed from parent to offspring | Trait |
| Traits that must be passed through DNA and cannot be changed | Inherited traits |
| Learned behaviors that are not passed through DNA | Acquired traits |
| Passing of traits from parent to offspring | Heredity |
| Study of heredity | Genetics |
| Stronger of two possible alleles, represented by a capital letter | Dominant |
| Gene that shows up less often in a cross, lowercase letter | Recessive |
| Gene combination for a trait, described by letters only (ex. BB, Bb, or bb) | Genotype |
| Physical feature resulting from a genotype (ex. brown eyes) | Phenotype |
| hybrid, both alleles are different | Heterozygous |
| pure bred, both alleles are the same | Homozygous |
| diagram used to predict probabilities of different offspring | Punnett Square |
| Scientist that first studied genetics in detail | Gregor Mendel |
| a synonym for homozygous | Pure Bred |
| a synonym for heterozygous | Hybrid |
| has a trait but it is not showing | Carrier |
| both phenotypes will show in a hybrid (ex. red and white spotted flowers) | codominance |
| both phenotypes will mix to produce a unique phenotype for hybrids (ex. pink flowers from white and red flowers) | incomplete dominance |
