Moreover, we find that polyploid species have more loci under positive selection, particularly in genes relating to chemical defence against herbivores, a key ecological pressure on tropical trees 🐛

nQuack was actually built for Larrea tridentata! I collaborate with @robertlaport.bsky.social and @jlandisbotany.bsky.social on population work for Larrea tridentata.

Find out more about nQuack here: mlgaynor.com/nQuack/ (5/n)

Allowing proportion (or alpha) to be free in our models allows us to use nQuack to estimate mode of inheritance - which is exactly what @rschley.bsky.social did in our new paper. Check it out here: doi.org/10.1111/nph.... (4/n)

Allopolyploids would not have ears, and instead have a large proportion of alleles with a frequency of 0.5 - which is beautiful illustrated by Lloyd and Bomblies 2016 Figure 1 (doi.org/10.1016/j.pb...). (3/n)

When I built nQuack, I wanted to be able to capture both allopolyploids and autoployploids - which differ in expected proportions of heterozygotes. Specifically, we expected autopolyploids to look like cats or dogs (2/n)

Gus was included too!

My second was last year during my first month as a postdoc and summarized some published + unpublished work: www.youtube.com/watch?v=GUGe...

My first polyploid webinar was in 2021 as a third year grad student and is on a project we still haven't published: youtu.be/mEvSgXN6jbs?...
