To date most genetic studies of introduced species have focused on evolutionary genetics [ 48, 49], genetic diversity [ 50], hybridization [ 51, 52], and the identification of source populations of species that are known to be introduced [e.g., [ 50, 53- 57].
Most genetic studies require tens of thousands of participants to carry enough statistical power to be considered meaningful.
"This is an example of one minority that has been ignored in most genetic studies," Dr. Comas said.
Friend's co-author Eric Schadt, of the Icahn school of medicine at Mount Sinai, said "Most genetic studies focus on finding the cause of a disease, but we see tremendous opportunity in figuring out what keeps people healthy.
Most genetic studies on the later Iron Age nomads, however, have been limited by small sample size, restricted to a single cultural group, or based on the analysis of mtDNA alone18,19,20,21,22.
Unfortunately, most genetic studies completely ignore strong nongenetic effects such as low education and poverty even though these factors are well-known to predict, for example, obesity.
Most genetic association studies have evaluated disease end points using case control study design (Collins 2009; Cordell and Clayton 2005; Suh and Vijg 2005; Zondervan and Cardon 2007).
Therefore, even as sequencing technology continues to improve, RAD marker sequencing will remain a useful and cost-effective tool for most genetic mapping studies.
When sample sizes of cases and controls increase to 1000 vs. 1000, which is currently not a problem for most genetic association studies, the model has almost full power to detect three-locus epistasis of different forms.
Most genetic association studies are based on a case-control design.
Most genetic association studies use an inadequate number of cases and controls and, therefore, lack the ability to draw firm conclusions on the observed associations.
