Expressivity
|
|
1. It is the % of individual organism having a particular genotype that express the expected phenotype.
|
1. It is the extent of a given genotype, expressing at the phenotypic level.
|
|
2. Quantitative measurement.
|
2. Qualitative measurement.
|
|
3. It explain how often the gene is expressed.
|
3. It explains at which extent gene is expressed.
|
|
4. Incomplete penetrance difficults the genetic analysis.
|
4. Variable expressivity difficults the genetic analysis.
