Happy to share my work with my advisor Zachary Szpiech! Why are associations between ROH & complex traits inconsistent across studies? We use realistic simulations to show how demographic history and genetic architecture interact to shape the phenotypic impact of ROH. www.biorxiv.org/content/10.6...

The Influence of Demographic History and Genetic Architecture on Complex Traits via Runs of Homozygosity

Runs of homozygosity (ROH) are contiguous genomic regions where all sites are homozygous, inherited from identical haplotypes due to shared ancestry. The number and length of ROH in individuals varies...

Dental Calculus Formation Is Linked to Diet and Phylogeny in Mammals
