Measuring selection and dominance in fitness of the insecticide-resistant Ace alleles in Drosophila melanogaster, the authors show evidence for beneficial reversal of dominance, a mechanism that can stabilize large-effect polymorphisms in nature. 🧪

Genome assembly is a software+data problem, and since the latest version of hifiasm, the best data is Oxford @nanopore data. github.com/chhylp123/hi...

Which assembly should be chosed `hifiasm HiFi+HiC+ONT->Cphasing Pore-C` or `hifiasm ONT` · Issue #874 · chhylp123/hifiasm

Hi, I used two assemble strategy, first version is hifiasm with HiFi+HiC+ONT data, then Cphasing scaffold with Pore-C data, second version is hifiasm with ONT data. However, first version genome ha...

A breathtaking coastal night scene with a sky full of stars. The calm ocean reflects the faint glow of the night, while rugged coastal rocks stand silhouetted against the horizon. In the distance, the first light of sunrise begins to emerge, casting a soft, golden hue that blends seamlessly with the deep blues and purples of the night. The atmosphere is serene and magical, capturing the quiet beauty of the transition between night and day.

#birds #costarica #nature

A striking bird perched on a slender branch in a lush green environment. Its body is adorned with deep black plumage, contrasting sharply with a vivid red head, neck, and chest. The bird’s small, stout beak is pale and sharply defined against its dark face, while its red eyes add an intense gaze. Tiny droplets of water cling to its feathers, suggesting a recent rainfall. The blurred green foliage in the background provides a natural, vibrant setting that enhances the bird’s brilliant colors.
