What is the PTC gene?
Genotype and Phenotype
TT- Taster. Those with the homozygous dominant trait usually taste extreme bitterness
Tt- Taster, those with the heterozygous trait can still taste bitterness, but it isn't as strong
tt- Non-taster. Those with the homozygous recessive trait can't taste anything.
How Do You Get The Trait?
The control group
During the experiment we first tested to see our phenotype. You must used a control in the experiment so that you can have a comparison to what would normally happen to what happens when you change something in the experiment. For this specifically, the control would be a piece of regular paper and the alternate would be the PTC paper.
