Neutral genetic diversity consists of genes that do not increase fitness and are not responsible for adaptability. Natural selection does not act on these neutral genes. Adaptive genetic diversity consists of genes that increase fitness and are responsible for adaptability to changes in the environment. Adaptive genes are responsible for ecological, morphological, and behavioral traits. Natural selection acts on adaptive genes which allows the organisms to evolve. The rate of evol… Web2 de abr. de 2024 · DOI: 10.1101/2024.03.30.534832 Corpus ID: 257927644; XMAP: Cross-population fine-mapping by leveraging genetic diversity and accounting for confounding bias @article{Cai2024XMAPCF, title={XMAP: Cross-population fine-mapping by leveraging genetic diversity and accounting for confounding bias}, author={Mingxuan Cai and …
