|
|
Term
|
Definition
| When an organism have two similar alleles for one gene |
|
|
Term
|
Definition
| When one allele expresses its characteristics in spite of the presence of a different allele(if red is dominant,then a red allele + white allele = red flower) |
|
|
Term
| Incomplete Dominance(dominus) |
|
Definition
| When a heterozygous organism displays a blending of both traits(if red and white are co-dominant,then a red allele + white allele = pink flower) |
|
|
Term
|
Definition
| When a heterozygous organism displays both traits at the same time(if red and white are co-dominant, then a red allele + white allele might produce patches of red and patches of white) |
