|---|---|
| Gregory Mendel | Modern science of genetics began with his work with peas |
| Genetics | study of biological inheritance |
| Trait | specifc characteristics (hair, eye color, etc) of an individual |
| Hybrid | the offspring of crosses between parents with different contrasting characteristics |
| Gene | a section of NA on a chromosome that codes for a trait |
| Allele | form a gene "Aa" |
| Gametes | reproductive cells |
| Homozygous | identical allels for one gene |
| Heteroxygous | different alleles for one gene |
| Phenotype | physical characteristics of an organism |
| Genotype | genetic makeup of an organism |
| Law of Segragation | each parent only give one allele to the offspring |
| Principle of Independent Assortment | inheritance of one pair of genes is independent of the inheritance of another pair of genes |
| codominace | the phenotypes for both alleles are clearly expressed |
| imcomplete dominance | one allele is not completely dominant over another |
| polygenic inheritance | traits controlled by two or more genes |
| multiple allele inheritance | many genes exist in more than two forms |
