也就是说,在大多数的情况下,选择消除了有害突变,并保持蛋白质不变(即纯化选择,purifyingselection)。 在少数情况下(通常当免疫系统基因与寄生虫共同进化时),我们发现Ka远大于Ks(即Ka / Ks >> 1)。这是有力的证据表明选择已经改变了蛋白质(正向选择,positive selection)。 我明白了,如果Ka等于Ks,那么序列的...

在少数情况下(通常当免疫系统基因与寄生虫共同进化时),我们发现Ka远大于Ks(即Ka / Ks >> 1)。这是有力的证据表明选择已经改变了蛋白质(正向选择,positive selection)。 我明白了,如果Ka等于Ks,那么序列的进化肯定是中性的? 没那么简单。中性进化是一种不可排除的可能性。但是,如果该基因的一部分(例如一个蛋白...
Phenology and plant architecture of spring lupin Lupinus albus L. vary with early thermal environment, which dramatically affects seed maturation and production. This study was conducted to develop and evaluate an index to quantify the relative differences among a selection of genotypes to "warm" and...
