GenotypicRichness |
Genotypic richness (G-1/N-1) of Zostera marina from one shoot per plot. Provided by J.Olsen. Genotypic richness ranges from 0 (all individuals the same) to 1 (all individuals different) and is a measure of the number of distinct genotypes. (Genotype = a clone.) Genotypes are multilocus with 8 16 or 24 loci involved.
