These three components perfectly separate the profiles belonging to each of the main ancestral continental populations.
Analyses were carried out in the present study in order to assess the performance of these panels when applied to three main HapMap continental populations, CEU, CHB, and YRI.
More than 2,000 complete genomes representing three main continental human population groups (Africa, Europe, and Asia) and two admixed populations ("African-Americans" and "Hispanics") were collected from GenBank and the literature, and were used as training sets.
We have used a simulation-based approach to evaluate the discrimination power of mtSNPs in different population contexts, including samples representing the main continental regions and admixed population groups.
The comparison of UK and continental demographies does not provide evidence of a single main bottleneck for the continental populations, but the viability of continental populations is endangered by the concurrent deterioration of reproduction and survival rates.
Unless specified, for most of the simulation experiments, only three populations representing the main continental groups were taken from the full HapMap data, namely CEU (European ancestry), CHB (East Asian ancestry) and YRI (African ancestry), with 50 individuals in each group.
The database used for the simulation experiments was built based on the following criteria: Selecting complete genomes from the literature and GenBank capable of being used as proxies of human population samples representing main continental regions.
The main cause of the observed crisis in continental populations of these birds should be looked for in the interaction between two factors - changes in livestock management, including the increased use of pharmaceutical products, and disease.
According to habitat characteristics, the period of study and the management practice the data were combined in two main subsets: the British populations from 1930 to the end of the 1960's and the "declining" continental populations from 1970 to the present.
A marriage of the two main continental exchanges would be likely to raise regulatory concerns.
