sci.population-genetics-hardy-weinberg Calculator
Tests whether population genotype frequencies conform to Hardy-Weinberg equilibrium using chi-square goodness-of-fit. Departure from HWE suggests selection, inbreeding, migration, or non-random mating — HWE is a null model for detecting evolutionary forces.
Inputs
Allele P Freq
Cycles per second (Hz). Audible sound: 20 Hz – 20 kHz. Make sure units match what the formula expects.
Sample Size
Number of data points collected. Larger samples give narrower confidence intervals. Rule of thumb: 30+ for most statistical tests.
Observed Aa
Reference formula or conversion factor shown for context.
Observed Aa Lower
Reference formula or conversion factor shown for context.
Results
χ² statistic
The value at the specified point or condition.
HWE?
Reference formula or conversion factor shown for context.
