Here's a reminder on #InternationalCoffeeDay: It's OK to take a (coffee) break. ☕

"It’s ... helpful to have a venue to share the day-to-day ups and downs of life as a grad student," a #PhD student wrote in this 2019 #ScienceWorkingLife. https://scim.ag/4nvLTBb

People arm in arm while drinking coffee and holding papers, with text: Why scientists should take more coffee breaks.

🚨 First pre-print from my team !!

TL;DR: presence of polymorphism (sequence differences between the homologous chromosomes) can *increase* the local rate of recombination in Arabidopsis thaliana, turning cold regions of the genome hot (purple v. grey) !

The recombination frequency (cM/Mb) along chromosome 4 of A. thaliana (female meiosis).

In full hybrids (grey), where polymorphism is distributed all along chromosomes, most crossovers occur in the regions surrounding the Centromere (Cen), and very few at chromosome ends (Tel: telomeres).

In lines where polymorphism is restricted to chromosome ends (purple), the local recombination rate increases drastically, at the expense of the non-polymorphic regions (yellow).
