Results: By χ2 we found the minor allele “G” of rs17050782 was with increased COPD risk in allele model.

In other words, genes that are close together on a chromosome are more likely to be inherited together as a unit than genes that are farther apart. pine lawn air conditionerNettetHowever, obtaining these blocks of SNPs through in vitro methods is both time consuming and expensive. In silico studies try to infer haplotypes from genotypic data. This thesis utilizes a genetic algorithm (i.e. a heuristic approach) guided through two genetic models, essentially the Hardy-Weinberg equilibrium and linkage disequilibrium. pine lawn court
