Answer:
No, I don't think so.
Step-by-step explanation:
I don’t think that Dr. Sammons will ultimately link genotype to phenotype because all the traits of an individual cannot be linked to the genes.
Genotype represents the genetic make-up of an individual while the phenotype represents the observable characteristics from an individual, either due to environment or genotype.
For example, certain behaviours in people are due to environment and external factors, not necessarily genes. In addition, resting heart rate may be linked to the genes but it will also depend on other factors in the body such as any heart condition or disease. However, height will be linked to the genes majorly but nutrition also plays major role.
So, it will be impossible to link happiness with the genes. On the other hand, resting heart rate and height may be linked to the genes up to a large extent.
