Answer 1

Answer:

Because of the inheritance mode patterns, the physical traits that are controlled by polygenic inheritance, such as hair color, height and skin color, as well as the non-visible traits such as blood pressure, intelligence, autism and longevity, occur on a continuous gradient, with many variations of quantifiable increments

Answer 2

We find continuous variation for both these traits because these traits are controlled by multiple genes. There are as many as 400 genes that control the trait of height and are responsible for variation in height present in the population.
