Biology
Shannon Diversity Index Calculator
Compute the Shannon (Shannon-Wiener) diversity index H' for three species from their abundance counts. Higher values indicate greater diversity; 0 means a single-species community.

Biology
Allele Frequency Calculator
Compute the frequency of a specific allele in a population from counts of each genotype (AA, Aa, aa). Commonly used in population genetics and Hardy-Weinberg equilibrium studies.
