Name the law that states that the sum of allelic frequencies in a population remains constant. What are the five factors that influence these values ?

Explanation

### Step-by-Step Solution:

1. **Identify the Law**: The law that states that the sum of allelic frequencies in a population remains constant is known as the **Hardy-Weinberg Principle**. This principle asserts that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.

2. **Understand the Implications**: The Hardy-Weinberg Principle implies that a population is in genetic equilibrium, meaning that the proportions of different alleles (gene variants) remain stable over time, provided that certain conditions are met.

3. **List the Factors Influencing Allelic Frequencies**: There are five key factors that can influence the allelic frequencies in a population, which can disrupt this equilibrium:
- **Mutation**: Changes in the DNA sequence that can introduce new alleles into a population. If mutations occur, they can alter the allelic frequencies.
