WebJan 15, 2024 · Gene diversity (h) also can be calculated for haploid data. Estimates of genetic diversity based on mitochondrial data, for example, often use h as a measure of haplotype diversity. In this context, h describes the numbers and frequencies of different mitochondrial haplotypes and is essentially the heterozygosity equivalent for haploid loci.
