Mendel's principles are related to

Options

A. Evolution
B. Reproduction
C. Variation
D. Heredity

Answer

**Step-by-Step Solution:**

1. **Identify the Subject of the Question**: The question asks about the principles established by Gregor Mendel and their relevance.

2. **Recall Mendel's Contributions**: Mendel, known as the father of genetics, conducted experiments on pea plants and formulated foundational principles of heredity.

3. **Understand the Key Concepts**: Mendel's work led to the formulation of three main laws:
- **Law of Segregation**: This law states that during the formation of gametes, the alleles for a trait segregate from each other so that each gamete carries only one allele for each gene.
- **Law of Independent Assortment**: This law states that the alleles of different genes assort independently of one another during gamete formation.
- **Law of Dominance**: This law states that in a heterozygote, one allele may conceal the presence of another allele.

4. **Determine the Correct Answer**: Since Mendel's principles primarily deal with how traits are inherited from one generation to the next, they are fundamentally related to heredity.

5. **Select the Appropriate Option**: Among the options provided (evolution, reproduction, variation, heredity), the correct answer is **heredity**.

**Final Answer**: Mendel's principles are related to **heredity** (Option 4).
