| Mendel | The Father of Genetics |
| gene | a piece of DNA, found on a chromosome that determines the inheritance of a trait |
| chromosome | located in the nucleus; made of DNA |
| dominant gene | in a pair of alleles, it's the trait that is physically shown; always uppercase letter |
| recessive gene | in a pair of alleles it's the one that is hidden if the dominant is present; always lowercase letter |
| allele | one of two forms of a gene (ex. T or t) |
| genotype | the genes of an organism |
| phenotype | physical traits of an organism |
| heredity | passing on traits from one generation to the next |
| heterozygous | having two different alleles for a trait |
| homozygous | having two identical alleles for a trait |
| mutation | a change in DNA or RNA |
| punnett square | a table used to predict the genetics of offspring between two parents |
