The GRFP announcement from NSF cuts out an entire cohort of 2nd year students from consideration, without warning. This is so deeply unfair that it warrants a formal protest from the scientific community. If someone wants to work with me to craft an open letter and solicit signatures, LMK.

New: After a long wait, the GRFP solicitation is live! Deadlines have been extended to early November, so applicants have a bit over a month to submit. www.nsf.gov/funding/oppo...

Heads up: ignore samtools dot org, similarly minimap2 dot com and likely others. It's owned by a known phishing site and while the binaries they offer look valid currently (but note they may be serving us different binaries to others), that could change.

Ie: it's not us (Samtools team)! Be warned

I’ll be advertising a post-doc position (up to 3 year) soon. It will be for somebody that is a good programmer, interested in evolution & is keen to learn new machine learning & AI approaches. I don’t have a link to a job advertisement yet. The post will be hybrid working and based at U of Liverpool

New preprint on the role of MutS2 genes in rescuing stalled/collided ribosomes in chloroplasts, led by Amanda Broz and many other contributors from the lab. Never expected to go down this road when we started working on plant MutS2 years ago. Feedback appreciated!

Slide showing definition of epistasis: Interactions between alleles at different loci. The phenotypic effect of an allele at one locus depends on which alleles are present at another locus in the genome.

Dan Sloan @sloanevolab.bsky.social · Sep 2
Cuz I thought epistasis only exists when there is variation at both loci, which is why the QG folks talk about "converting" epistatic to additive variance when an allele is fixed at one locus. Dude, all I know is that my confidence is shot next time I teach the Genetics kiddos about epistasis. Ha.

Don't you also need Ab and ab to show that it's an interaction?

sloanevolab.bsky.social
Dan Sloan @sloanevolab.bsky.social · Sep 1
By that, you mean an alelle at each of two different loci? I don't think you can have epistasis until you consider that there is an alt allele (WT?) at each of those loci. I think of epistasis as being defined between loci, not between alleles, and it could not be done with only two haplotypes.

sloanevolab.bsky.social
Dan Sloan @sloanevolab.bsky.social · Sep 1
I guess one difference is that you can have a dominance relationship with just two alleles (e.g., one of your mutants and WT). But you couldn't have epistasis if there were just those two alleles.

sloanevolab.bsky.social
Dan Sloan @sloanevolab.bsky.social · Sep 1
But if you consider the sites of the mutations to be diff loci, you have one epistatic relationship between 2 bi-allelic loci to define. Both seem like reasonable framings, but I don't see how that makes dominance = epistasis? I might be misunderstanding tho.

sloanevolab.bsky.social
Dan Sloan @sloanevolab.bsky.social · Sep 1
I think dominance is defined for pairs of alleles. In your two-mutant (A and a) example, you would also have a WT allele, so there are 3 dominance relationships (A vs a; A vs WT; a vs WT) to define.
