|
Definition
| Diagrammed family history that is used to study inheritance patters of a trait through several generations and that can be used to perdict disorders of the future offspring |

Term
|
Definition
| Complex inheritance pattern in which the hetereozygous phenotype is intermediate between those of 2 homozygous parent organisms. EX: white flower with a red flower makes a pink flower |
