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.
People with this form of albinism have white hair, light-colored eyes, and very pale skin that does not tan. Other mutations in the TYR gene reduce but do not eliminate tyrosinase activity. These mutations, which allow some melanin to be produced, cause oculocutaneous albinism type 1B (OCA1B).
