The genomic bases, or architectures, of complex traits are… complex. But what if by overestimating the complexity of some aspects of the genomic architecture of a trait, we’re actually underestimating the complexity of its evolutionary dynamics? This notion struck me when two things clicked while I was preparing a fellowship application back in 2017. First, […]

A horse of a different color patterning mutation
Connecting genotypes to the complex phenotypes they produce is a fundamental goal of genetics. Variation in coat color pigmentation, partly due to the relative ease at which different patterns can be identified, is one of the best-characterized traits at the genetic level, with examples from sheep (Zhang et al., 2017), cattle (Li et al., 2016), […]
Is European bison really back?
Humans constantly interact with their environment. They modify habitats, transfer species from one place to another, domesticate some species while contributing to the extinction of others. To reverse the process of extinction, we’ve been reintroducing taxa since the 1800s. Reintroduction refers to the action of establishing self-sustaining and healthy populations of extinct or critically endangered […]
To band or not to band: what drives the expression of fashion accessories in female pipefish?
“Tale as old as time. Female chooses male. Male is large in size. Male has weaponry. Unsurprisingly! Male’s ornamentation. Male’s behavior. Female makes the eggs. Takes care of the young. Male and female roles.”1 But not all the time! 1Adapted from Disney’s “Beauty and the Beast” written by Howard Ashman As the female is usually […]
Studying the genetics of migration using hybrids from a migratory divide
Every spring, nature enthusiasts are excited for another bird migration made evident by the countless posts on social media noting rare warblers spotted in backyards and high species counts on birding trips. And the excitement is warranted, as migration is an amazing feat, both ubiquitous and complex, requiring coordination of numerous adaptations for the birds […]
