Demographic modeling using genetic data can estimate changes in long-term population sizes while temporal sampling provides a way to compare genetic variation present today with that sampled in the past.
These cell lines additionally display various mutations in their genome with LNCaP and PC3 cells having inactivated PTEN (Phosphatase and tensin homolog) and MDA-PCa-2b cells having intact PTEN [ 7, 8].These differences are used to model the variation present in patients with differing stages of disease progression.
Working with a very narrow species concept, and not being familiar with the variation present in natural populations, Burret placed almost every specimen into a distinct species.
It is noteworthy to point out that all the Caucasian samples fall into just one sub-clade, M1a1b2, with no variation present at the intermediate level of resolution (Additional file 3), signature of a likely founder effect.
The genomic positions of these SNVs are distributed nonrandomly, with more variation present on chromosome arms than in the centers where recombination is lower (Koch et al. 2000; Wicks et al. 2001).
In general, the strongest evolutionary responses to climate change will likely occur in species with short generation times, subject to high or consistent selection pressure, especially near peaks of natural cycles, and in traits controlled relatively simply or with genetic variation present in existing populations.
Seventeen different haplotypes were also seen, with haplotype frequency 0.65 for the major haplotype 1 with no ATM variation present in the exonic and adjacent intronic regions studied.
When working with biological data, one of the biggest challenges lies in trying to deal with the extensive variation present in the samples.
In Fig. 4 since the configuration of Femtocell 1 and Femtocell 2 are identical, the capacity variation presents a symmetrical trend with P 1 and P 2 variation.
This measure considers that the words with little variation presents little discriminant power, as they occur in a uniform way in the whole collection.
