问题 我想问一下在进行WGD分析时,要算复制时间,基于物种进化速率的公式:The divergent time of the whole-genome triplication (WGT) event was calculated using the formula divergence dateKs / 2r.

Based on the divergent time (77 million years ago) between F. americana and C. canephora and the mean Ks value (1.36) of syntenic gene pairs between F. americana and C. canephora, it estimated 8.83 × 10−9 substitutions per site per year of synonymous nucleotide substitutions rate (r) fo...
