Change of frequency of alleles in a population results in evolution is proposed in `:`

Options

A. de vries theory
B. Darwin's theory
C. Lamarck's theory
D. Hardy-Weinberg principle

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question is asking which theory proposes that a change in the frequency of alleles in a population leads to evolution.

2. **Analyzing the Options:**
- **Option 1: De Vries Theory** - This theory is associated with mutations and does not specifically address allele frequency changes leading to evolution.
- **Option 2: Darwin's Theory** - While Darwin's theory focuses on natural selection, it does not directly propose that changes in allele frequencies are the primary mechanism of evolution.
- **Option 3: Lamarck's Theory** - Lamarck's theory discusses the inheritance of acquired characteristics, which does not relate to allele frequency changes.
- **Option 4: Hardy-Weinberg Principle** - This principle describes how allele frequencies remain constant in a population under certain conditions, and it also implies that any change in these frequencies can lead to evolution.

3. **Identifying the Correct Answer:**
The correct answer is **Option 4: Hardy-Weinberg Principle**. This principle states that changes in allele frequencies in a population can lead to evolutionary changes.

4. **Conclusion:**
Therefore, the change of frequency of alleles in a population resulting in evolution is best explained by the Hardy-Weinberg Principle.
