Using an integrative approach combining genetic and association mapping, transcriptome and genome sequencing, and gene expression analyses, we show that a single gene, doublesex, controls supergene mimicry in Papilio polytes.

Experimental crosses show that such Dobzhansky–Muller incompatibilities (DMIs) are often complex (involving alleles at three or more loci) and asymmetrical (such that reciprocal introgressions have very different effects on fitness). One possible explanation is that asymmetrical and complex DMIs are ‘easier to evolve’, because they block fewer of the possible evolutionary paths between the parental genotypes.

“I’d like to think that people want to work with me because of what I can bring to the table other than my data, but I’m not keen on testing that working hypothesis.”

“So I say suck it up, share the data behind the paper, manage your data well, and let’s all get on with our lives.”

“Ask anyone in academics whether you’d rather have 6 citations from awesome papers or 6 awesome papers and 100% of them will take the papers.”

“This is an R wrapper to the NOAA climate data API.”

“I would like to place a vertical bar next to all the tips descended for a node that I specify [on my phylogeny]. How do I do this?”
