**Introduction:** The Effective Size Calculator is a valuable tool in genetics, ecology, and conservation biology. It helps researchers understand the genetic dynamics of populations by estimating the effective population size, denoted as Ne.

**Formula:** The effective population size (Ne) is calculated using the formula: Ne = (2 * N1 * N2) / (N1 + N2), where N1 is the total population size and N2 is the breeding population size.

**How to Use:**

- Enter the total population size (N1).
- Provide the breeding population size (N2).
- Click the “Calculate” button to obtain the effective population size (Ne).

**Example:** Suppose you have a total population of 500 individuals (N1) and a breeding population of 150 individuals (N2). Use the calculator to find the effective population size.

**FAQs:**

**Q:**What is the significance of effective population size?**A:**Ne reflects the genetic diversity and potential for adaptation in a population, crucial for understanding evolutionary processes and conservation planning.**Q:**Can the effective population size be larger than the total population size?**A:**Yes, the effective population size can be smaller, equal to, or larger than the total population size, depending on factors such as breeding patterns.

**Conclusion:** The Effective Size Calculator simplifies the estimation of Ne, aiding researchers in making informed decisions based on population genetics principles. Utilize this tool to explore genetic diversity within populations and contribute to effective conservation strategies.
