This is a question on statistical methods used in DNA research
Lately, many plant species are changing from species, genera, or even families due to studies in molecular makers. For example, teak and gmelina tree species were changed from Verbenaceae to Lamiaceae. The old Bombacopsis quinatum was changed first to Pachira quinata and now to Pochota fendlery. In the case of Orchids, the species of the genera Cattleya, Laelia, Schomburkia, and Sophronitis are suffering continuous changes in the classification of the various species within these genera. How sound are statistical techniques used to ensure these are real differences. What is the sampling method used?
Dear Prof. Mauricio Jerez,
Good day,
POPGENE (population genetic analysis) has to be used to estimate the genetic structure parameters for each marker total loci, polymorphism loci and percentage, Shannon's Information Index (I), gene diversity (H) Nei's, Effective number of alleles (Ne) and Observed number of alleles (Na). Analysis of molecular variance (AMOVA) must be estimated using GenAlEx.
Dear Dr Jerez, I think NCBI includes many softwares should work for this purpose . check it to do.
Dear Dr. Jerez,
Perhaps you are familiar with the term DNA Barcoding. This method is not an alternative for classical taxonomy but rather a addon to increase the stringency of taxonomic study. With the advent and use of this technology it has been seen that many plant/ animal species although have tremendous physiological similarity, but they represent two far off families genetically. And the exact opposite phenomenon has also been seen. Huge amount of work in this field is going on across the globe, which you can find out online.
