What is genetic differentiation and genetic structure?
Answers
Genetic diversity is the total amount of variation in a population (or among populations). Population structure is how those variants are distributed. For example, if you use the simple case of two alleles in a population, they may be at 0.5 Heterozygosity (which is one measure of diversity), or 50% frequency of each allele. But one allele may be fixed in one population, the two at 50/50 frequency in another, and fixed for the alternate allele in yet another.
The minimum number of samples to detect structure will depend on the amount of variation in the populations you're measuring, the type of data, and the specific measure of structure you're using, but a good general rule of thumb is 15-30 samples for diploid data. Obviously larger samples are more reliable, but over 30-40 the increase in accuracy will generally start to plateau
Explanation:
and genetics is the study of transmission of body features both similarities and differences from parents to offspring and the laws relating to such transmission
