How many different trees can be generated by just one duplication event? It turns out A WHOLE LOT, if you consider the coalescent process.

following on from that, when you use single cell data, you should bear in mind the different biases of snRNAseq vs scRNAseq - this lnc effect being one, also different expectations about intron/exon ratios in read mapping (which in my experience can be huge). 3/3
22.01.2026 21:23 β π 2 π 0 π¬ 1 π 0So imho, we THOUGHT they were rarer than they are because of recovery bias. That gets exponentially more complex when you consider that a bunch of lncRNAs will be cell type specific, biasing it even further. /2
22.01.2026 21:23 β π 2 π 0 π¬ 1 π 0One realisation I had while looking at the lncRNA ivory in single nucleus data: lncRNAs are generally nuclear, so in bulk RNAseq they are depleted because the nuclei make up a small volume of what gets extracted. In single nucleus RNAseq you will thus massively enrich any such transcripts. 1/

A few years ago, through luck and vibes, I managed to produce this blue colored bean variety.
This was an early step in trying to answer the question, [paraphrased] "Why isn't blue as common as red in beans, even though they're both anthocyanins and the plant has the genes for both?"
Hypotheses of stripe pattern homology between nymphalids and hesperiids. (A) Current summary of the nymphalid ground plan, mainly based on the terminology of Schwanwitsch (Nijhout, 1991; Schwanwitsch, 1924) and including recent updates by Otaki and Mazo-Vargas et al. (Mazo-Vargas et al., 2017; Otaki, 2012; Otaki, 2021; Schwanwitsch, 1956). Discalis elements (D1 and D2); CSS, central symmetry system (cyan); BoSS, border ocelli symmetry system (magenta); Oc, forewing border ocelli; pPf and dPf, proximal and distal parafocal elements; MBS, marginal band system (green). Colored vignettes denote vein intersection landmarks. Magenta square, junction between R and M vein trunks; yellow dot, M1-M2 junction; red star, junction between discal crossvein and M3; blue cross, M3-Cu2 junction; green triangle, Cu1-Cu2 junction. Rectangles feature the name of marker genes. (B) Ventral wing patterns of the nymphalid Prepona eugenes with ground plan annotations proposed by Schwanwitsch, 1956 (left: reproduction of published drawings; right: equivalent annotations as color overlays). (C) Phylogenetic relationship between Papilionoidae families. (D) Ventral wing patterns of the hesperiid P. sidae annotated as in panel A, and highlighting the inferred CSS predicted by Schwanwitsch, 1956 (left panel). According to this author, the CSS marks a grey pattern in forewings, and a dislocated white stripe pattern in hindwings, suggesting uncoupling of pattern and color state in fore/hindwings in skippers. The forewing CSS is markedly dislocated along the Cu1 vein (arrowhead).
#WntA is a crucial marker of stripe elements early in development for the Nymphalidae butterfly family. @jasminealqassar.bsky.social & co explore if WntA has maintained its role in stripe elements over 95 million years of evolution in the Hesperiidae family of butterflies. doi.org/10.1242/bio....
