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.
5. Describe the expression of single gene
