| phenotype | the actual characteristics that can be observed in an organism |
| genotype | the genetic makeup of an organism |
| homozygous | 2 of the same alleles for a trait |
| heterozygous | 2 different alleles for a trait |
| dominant | allele that will show up in the phenotype even if only 1 copy is present |
| recessive | an allele that will show up in the phenotype only if there is no dominant allele to mask it |
| alleles | various forms of the same gene |
| sexual reproduction | a type of reproduction in which a cell from the mother combines with a cell from the father, combining the DNA for a new offspring |
| homolog | one of each chromosome in a pair |
| gene | a unit of herdity found in a specific place on a chromosome |
| Punnett Square | A tool used to figure out the probability of offspring's genotypes |
| Gregor Mendel | Used pea plants to study how traits are passed from parents to offspring |
| heredity | The passing of traits from parents to offspring |
| inherited trait | Traits that are passed form parent to offspring through DNA |
| acquired trait | trat that develops later in life |
