Some individuals with blood group A may inherit the genes for blond hair, while other individuals with blood group A may inherit the gene for brown hair. This can be best explained by the principle of

Options

A. Dominance
B. Multiple alleles
C. Independent assortment
D. Incomplete dominance

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question states that individuals with blood group A can have different hair colors (blond or brown). This suggests that the traits for blood group and hair color are inherited independently.

2. **Identifying the Principle**: The principle that explains this phenomenon is Mendel's Law of Independent Assortment. This law states that alleles for different traits segregate independently from one another during the formation of gametes.

3. **Explaining the Law**: According to Mendel's Law of Independent Assortment, the inheritance of one trait (like blood group) does not affect the inheritance of another trait (like hair color). This means that the allele for blood group A does not dictate the allele for hair color.

4. **Conclusion**: Therefore, individuals with blood group A can inherit different alleles for hair color (blond or brown) independently of their blood group. This independence allows for a variety of combinations of traits.

**Final Answer**: This can be best explained by Mendel's Law of Independent Assortment.
