When choosing themes for a Quarto page, is there a way to check whether the palette is colour blind friendly? I’m having fun going through all the themes, but I want to make sure it’ll actually work for everyone #Rstats #Quarto

Help please science people! Is this worryingly off? Amplification of V1-V9 of 16S rRNA. It should amplify at 1465 bp, but has amplified at > 1500 bp… 0.8% gel, 90V for 60 mins, DNA samples of Medfly tissues. I think am too naive to know if it is ok… Thank you! #PCR #MolecularBiology #Microbiome
