1. What is G5 Allele Frequency?

The G5 allele frequency represents the proportion of G5 alleles in a given population relative to all alleles at that locus. It's a fundamental measure in population genetics.

2. How Does the Calculator Work?

The calculator uses the allele frequency formula:

\[ Freq = \frac{count\_G5}{total\_alleles} \]

Where:

Explanation: The equation calculates the simple proportion of G5 alleles in the population sample.

3. Importance of Allele Frequency Calculation

Details: Allele frequencies are crucial for understanding genetic variation, population structure, and evolutionary processes. They help identify genetic markers associated with traits or diseases.

4. Using the Calculator

Tips: Enter the count of G5 alleles and the total number of alleles sampled. Both values must be non-negative integers, and total alleles must be greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What does an allele frequency of 0 mean?
A: A frequency of 0 means the G5 allele was not observed in your sample, though it might exist at very low frequencies in the population.

Q2: What's considered a high allele frequency?
A: This depends on context. In general, frequencies above 0.05 (5%) are considered common variants, while lower frequencies represent rare variants.

Q3: How large should my sample be?
A: For accurate frequency estimates, larger samples (typically hundreds to thousands of individuals) are preferred to minimize sampling error.

Q4: Can frequency exceed 1?
A: No, allele frequencies range from 0 to 1, representing the proportion of that allele in the population.

Q5: How is this different from genotype frequency?
A: Allele frequency counts individual alleles, while genotype frequency counts combinations of alleles in individuals (e.g., homozygotes and heterozygotes).
