Answer:

The correct answer would be "they are polygenic traits".

Polygenic traits are those which are controlled by at least two different genes.

As more than two genes are involved in controlling a single trait, so they show more variations as compared to the traits which are controlled by a single gene.

For example, height is controlled by at least three genes and thus six alleles are involved in regulating height.  

Polygenic traits often show a bell-shaped curve in a population.

Answer: Succinate dehydrogenase

Explanation: succinate dehydrogenase or Complex II or succinate-coenzyme Q reductase is an enzyme complex involved in citric acidic cycle, bound to the inner mitochondrial membrane of mammalian mitochondria and cell membrane of many bacterial cells. It is the only enzyme that participates in both the citric acid cycle and the electron transport chain. This enzyme catalyzes the oxidation of succinate to fumarate with the reduction of ubiquinone to ubiquinol, reaction occurs in the inner mitochondrial membrane by coupling the two reactions together.
