Genetic Dissection of Heritable Traits in Yeast Using Bulk Segregant Analysis.

Journal Article (Journal Article)

Bulk segregant analysis (BSA) is commonly used to determine the genetic basis of complex traits in yeast. This technique involves phenotyping progeny from a cross and then selectively genotyping pooled subsets of offspring with extreme phenotypes. Analysis of these genotype data can identify loci that show skewed allele frequencies in a group of phenotypically extreme individuals and that are likely to contribute to a trait. BSA can be applied to diverse strain crosses, including ones involving nonreference isolates. Further, given the high throughput of next-generation sequencing, it is possible to conduct many BSA experiments in parallel. Here, we present a BSA protocol for the generation of recombinant cross progeny. We then describe general BSA strategies for conducting phenotyping, causal loci detection, and candidate gene identification in a statistically powerful manner.
