Chapter 5: Heredity
| Question | Answer |
|---|---|
| Heredity | Passing of traits from parent to offspring |
| Allele | A different form a gene may have for a trait |
| Genetics | The science of how traits are inherited through alleles passed from one generation to another |
| Dominant | The form of a trait that appears to dominate or mask another form of the same trait |
| Reccessive | The form of a trait that seems to disappear when a dominant trait is present |
| Punnett Square | A tool that shows how genes can combine; used to predict the probability of types of offspring |
| Genotype | The genetic makeup of an organism for a trait |
| Homozygous | An organism that has identical alleles for a trait |
| Hetrozygous | An organism that has two different alleles for a trait |
| Phenotype | A physical trait that shows as a result of an organism's particular genotype |
| Incomplete Dominance | The production of a phenotype in an offspring that is intermediate to the phenotypes of its two homozygous parents |
| Multiple Alleles | Having more than two allele that control a trait |
| Polygenic Inheritance | Occurs when groups of gene pairs act together to produce a specific trait |
| Sex-linked Gene | An allele inherited on a chromosome |
| Pedigree | A diagram that shows the occurrence of a trait in a family |
| Genetic Engineering | Biological and chemical methods to change a cell's DNA sequence to produce desirable traits or eliminate undesirable traits |
| Genome | A map of the location of individual genes on every chromosome of an individual |
