Inheritance of skin colour in human beings is an example of -

Options

A. polygenic inheritance
B. Mendelian inheritance
C. monogenic inheritance
D. complementary genes

Answer

**Step-by-Step Solution:**

1. **Understanding Skin Color Inheritance**: Skin color in humans is determined by multiple genes, rather than a single gene. This means that several genes contribute to the final phenotype (observable traits) of skin color.

2. **Defining Polygenic Inheritance**: When a trait is controlled by more than one gene, it is referred to as polygenic inheritance. In the case of skin color, multiple genes interact to produce a range of skin tones.

3. **Differentiating from Monogenic Inheritance**: In contrast to polygenic inheritance, monogenic inheritance is when a trait is controlled by a single gene. Skin color does not fall into this category because it is influenced by multiple genes.

4. **Conclusion**: Therefore, the inheritance of skin color in human beings is an example of polygenic inheritance.

**Final Answer**: Inheritance of skin color in human beings is an example of polygenic inheritance.
