Rating Newest Oldest. Best Answer: Polygenic Inheritance: Human skin color is a good example of polygenic (multiple gene) inheritance. Assume that three dominant capital letter genes (A, B and C) control dark pigmentation because more melanin is produced.
Although humans are sometimes divided into races, the morphological variation between races is not indicative of major differences in DNA. For example, recent genetic studies show skin color may drastically change in as few as 100 generations, spanning 2,500 years, as a result of environmental influences. Furthermore, the DNA of two humans chosen at random generally varies by less than 0.1 percent. This is less genetic variation than other types of hominids (such as chimpanzees and orangutans), leading some scientists to describe all humans as belong to the same race â the human race.
