| A | B |
| genetics | study of heredity and mechanisms by which traits are passed on |
| heredity | passing of traits from parents to offspring |
| true breeding | organism that is homozygous for a trait and produces offspring w/same pheno |
| P generation | parental generation |
| F1 generation | first generation |
| F2 generation | second generation |
| dominant | allele that masks the recessive trait |
| recessive | allele that is expressed only if the dominant isn't present |
| law of segregation | pairs of alleles separate in meiosis (ex. Tt separate) |
| law of independent assortment | pairs of homologous chromosomes separate during meiosis (traits separate) |
| alleles | alternate forms of a gene |
| genotype | genetic make up of an organsim |
| phenotype | organism's appearance/physical traits |
| homozygous | individual that has identical alleles for a trait |
| heterozygous | individual that has two different alleles for a trait |
| monohybrid cross | cross using only one trait |
| dihybrid cross | cross using two traits |
| Punnett square | tool used to predict results of a genetic cross |
| test cross | crossing of an individual with unkown genotype with a recessive individual |
| incomplete dominance | dominant trait that doesn't fully mask the recessive, result is a blend |
| codominance | 2 different alleles for a trait are competely expressed in the offspring |
