Population genetic analyses of 103 SARS-CoV-2 genomes indicated that these viruses evolved into two major types (designated L and S), that are well defined by two different SNPs that show nearly complete linkage across the viral strains sequenced to date. Although the L type (∼70%) is more prevalent than the S type (∼30%), the S type was found to be the ancestral version. Whereas the L type was more prevalent in the early stages of the outbreak in Wuhan, the frequency of the L type decreased after early January 2020. Human intervention may have placed more severe selective pressure on the L type, which might be more aggressive and spread more quickly. On the other hand, the S type, which is evolutionarily older and less aggressive, might have increased in relative frequency due to relatively weaker selective pressure. 0055イドクスウリジン(庭) [TH]2020/03/05(木) 07:17:08.42ID:YnCNwH6R0https://i.imgur.com/nchrTKJ.jpg0056ダクラタスビル(東京都) [US]2020/03/05(木) 07:17:15.26ID:yPC0E+wH0 猛追が始まる 0057パリビズマブ(東京都) [BR]2020/03/05(木) 07:17:15.99ID:kc8QaxLw0 じゃあ今世界で流行してるのも 日本発なのか!? ってこと? 0058アタザナビル(栃木県) [ニダ]2020/03/05(木) 07:17:26.07ID:ndziwkLr0>>48 横からだが事実だよ 0059アタザナビル(神奈川県) [US]2020/03/05(木) 07:17:51.08ID:2cjpmmL+0 定期的に中国では政権争いに負けた人たちとか いろんな理由で逃げてきた人たちが 海を渡って逃げてきて日本にたどり着いてるからな^^ 仏教の伝来とかもあるし ザビエルさんみたいなイエズス会とかも来るわけだし 0060オセルタミビルリン(神奈川県) [EG]2020/03/05(木) 07:18:10.37ID:7y9Xj4Bn0>>22 未知の感染症だから 何がどうなてるのかわからからね 国の危機管理能力が試されてる
