这个工具适合做什么
Use it to estimate Ne from breeding male and female counts.
- Assess breeding population structure.
- Compare sex-ratio scenarios.
- Plan conservation genetics notes.
根据性别比例或世代变化估算有效种群大小(Ne)。
Ne = 4NmNf / (Nm + Nf)输入已知数值后,计算器会使用该公式给出主要结果,并提供辅助指标帮助你检查结果是否合理。
| Symbol | Variable | Description |
|---|---|---|
| males | Breeding males (Nm) | Breeding males (Nm) used by the calculator. |
| females | Breeding females (Nf) | Breeding females (Nf) used by the calculator. |
输入已知数值
按字段填写数值,并确认单位与页面公式一致。

解读结果
Balanced sex ratios keep Ne closer to census size; uneven ratios reduce effective population size.
Use it to estimate Ne from breeding male and female counts.
Balanced sex ratios keep Ne closer to census size; uneven ratios reduce effective population size.
This sex-ratio model does not include variance in family size or overlapping generations.
