| A | B |
| heredity | the passing of traits from parent to offspring |
| allele | different forms a gene may have for a trait |
| genetics | the study of how traits are ingerited through the action of alleles |
| dominant | the form of a trait that appears to dominate or mask another form of the same trait |
| recessive | the firn if a trait that seems to disappear in a population but can reappear depending on the way the alleles combine |
| Punnent square | a tool used to predict results in Mendelian genetis |
| genotype | the genetic makeup |
| homozygous | an organsm with two alleles for a trait that are exactaly the same |
| heterozygous | an organism that has two different alleles for a trait |
| phenotype | the physical trait that shows as a result of a particular genotype |
| purebread | an organism with 2 alleles for a trait |
| hybrid | an organism that has 2 different alleles for a trait |
| incomplete dominance | the production of a phenotype that is intermediate to those of the two homozygous parents |
| multiple alleles | having more than two alleles that control a trait |
| polgenic inheritance | occurs when groups of gene pairs act together to produce a specific trait |
| TRAIT | physical characteristics |
| DOMINANT | in control trait |
| RECESSIVE | wimpy trait |
| PUREBRED (HOMOZYGOUS) | alleles same |
| HYBRID (HETEROZYGOUS) | alleles different |
| PHENOTYPE | what you see |
| GENOTYPE | genetic make-up |
| GENE | controls traits |
| ALLELE | letters |
| PUNNETT SQUARE | predicts offspring |
| PROBABILITY | chance of something happening |
| P1 GENERATION | original cross (1st) |
| F1 GENERATION | offspring of P1 |
| INCOMPLETE DOMINANCE | a blending of 2 dominant traits |
| MULTIPLE ALLELES | more than 2 alleles ex.blood type |
| POLYGENIC INHERITANCE | more than 1 gene pair controls a trait |
