| gene | units for individual traits |
| allele | a pair of genes for a trait |
| probability | the odds that somthing will occur |
| dominant | the controlling gene |
| Mendel | the father of modern genetics |
| genetics | the study of heredity |
| hybrid | having one dominant and one recessive gene |
| genotype | ones genetic makeup |
| heredity | study of how characteristics are passed from one generation to another |
| incomplete | type of dominance where 2 genes are expressed, but not equally |
| recessive | hidden gene which only showsup in a in a homozygous state |
| gametes | reproductive cells |
| chromosome | "X" shaped units of heredity |
| Punnett | used a grid to study heredity |
| test cross | used to determine the genotype of the parents |
| trait | a physical characteristic |
| purebred | common term for homozygous |
| phenotype | ones physical appearence |
| codominance | type of dominance where 2 genes are equally expressed |
| crossover | occurs when alleles from one chromosome moves to a homologous chromosome |
| mutation | produces a perminant change to the genome |
| transposon | occurs when one allele pair moves, completely, from one location to another |
| karyotype | analysis tool for examining genetic anomalies |
| haploid | number used to describe the genomic makeup (total) of a gamete |
| centromere | structure which holds two alleles together forming a chromosome |
| independant | type of assortment where alleles from different traits are randomly assorted |
| pedigree | analysis tool used to study inheritance in a family |
| diploid | number assigned to a cell with a complete set of alleles (body cell) |
| polyploidy | condition that occurs in plants when they have extra sets of chromosomes |
| segregation | term used to describe the separation of the alleles in meiosis |
