what are the three main reasons for GWAS
advances in genotyping and sequencing technology
most diseases are probably controlled by many mutations
linkage mapping is inadequate because you want to find specific alleles
more recombination reduces correlations between DNA variants and leads to higher or lower resolution?
higher
why do you want to study non related relatives in GWAS?
because want most recombination possible
what are the main challenges of GWAS?
false positives
hidden populations
epistasis
environmental factors
epigenetics
what are the keys motivators for GWAS
drug targets
locate previously unsurveyed DNA variants through their correlations with those that are already surveyed
T or F. heritabilites are population specific
true
what are the steps of association studies
ID sample in population
measure disease status and underlying risk factors
genotype for SNPS
test differences in trait among genotypic class
resequence and further investigate
