Genetics of Complex Traits

Most important traits are complex and we study the genetic architecture of several such traits to explore the connection between genotype and phenotype. We have performed quantitative trait locus mapping of behavioral traits (the rate of behavioral ontogeny and sucrose responsiveness), and ovary size in worker honey bees, which plays an important role in phenotypic differentiation among workers. More recently, we have also performed transcriptome studies to get a system level understanding of different behavioral states and we are also turning our attention to traits that are relevant to honey bee health, such as stress responses, virus resistance, and disease progression.
