The major unsolved problem of descriptive population genetics is an adequate specification the genetic difference between two closely related species as compared to populations same species. Traditional analyses deal with distribution allele frequencies and within populations. From these several measures structure can be estimated, one most widely used being distance measures. Genetic degree gene (genomic difference) or that measured by some numerical method. have already been established...

Dependence is an important issue because traditional analysis approaches, such as of variance and ordinary least square regression, assume independence individual scores they can produce biased parameter estimates standard errors if applied incorrectly to dyadic data. A number analytical techniques that estimate the degree dependence in data are available.
