Question

Dr. Sammons has been stealthily performing a PheWAS experiment in all of his ABIO 329 classes. He genotypes all of the members of the class and then asks what genotypes are associated with certain phenotypes. There are 132 students in the class and Dr. Sammon measures these phenotypes directly after the final exam. For each of the three phenotypes being measured, describe if you think Dr. Sammons will ultimately link genotype to phenotype why? Hint: Dr. Sammons thinks there is a different rationale for all three.
A) Happiness
B) Resting Heart Rate
C) Height

Answer 1

Answer:

No, I don't think so.

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.
