From: Genetic diversity and resilience in benthic marine populations
Sigla | Name | Definition |
|---|---|---|
MLG | Multi-locus genotype | Number of unique multi-locus genotypes |
R | Genotypic diversity | Number of unique multi-locus genotypes relative to the number of samples collected |
PLP | Percentage of polymorphic loci | Fraction of polymorphic loci within the sample |
NHL | Number of heterozygous loci | Number of heterozygous loci for each unique multi-locus genotype |
H | Heterozygosity | The proportion of heterozygous loci at the individual level |
Ho | Observed heterozygosity | The proportion of N samples that are heterozygous at a given locus |
He | Expected heterozygosity | The proportion of heterozygosity expected under random mating |
Hj | Heterozygosity | The probability that two genes, randomly drawn from population j, differ at the ith locus |
Hnb | Unbiased heterozygosity | Expected heterozygosity corrected; estimated on the set of MLL defined after removing ramets derived from the same zygote ancestor according to psex(fis) |
Diploide | Diploide | Organisms have two alleles per locus (identified by the presence of at least one heterozygous locus) |
Heterozygous (MDH and GPI-2) | Heterozygote at the MDH and GPI-2 | Individuals that have two different alleles at the malate dehydrogenase (MDH) and glucose-6-phosphate isomerase (GPI) |
Heterozygous (MDH) | Heterozygote at the MDH | Individuals that have two different alleles at the malate dehydrogenase (MDH) |
Heterozygous (GPI-2) | Heterozygote at the GPI-2 | Individuals that have two different alleles at the glucose-6-phosphate isomerase (GPI-2) |
AR | Allele richness | Number of alleles per locus and population, corrected for sample size |
D. Cohorte | Cohort diversity | The number of independent juvenile cohorts created from different adult source populations or parents |
GR | Genetic relatedness | Genetic similarity among individuals within and across cohorts |
Fis | Inbreeding coefficient | The correlation between genes on uniting gametes relative to the total array of those in random derivatives of the foundation stock |
Pareto B | Pareto B | β is derived from the slope of Pareto distributions |
Pareto Max | Pareto Max | Maximum number of clonal replicates |
D | Simpson’s genotype diversity index | The probability of encountering distinct Multi-Locus Genotypes (MLG) when randomly taking two sample units |
CR | Clonal sub range | The maximum distance in meters between two identical genotypes belonging to the same clone |
Set | MLG, R, AR, Na, Ho and He | Set of diversity measures that include MLG, AR, Na, Ho and He |
