Re: Re:

so, it is difficult to estimate the diverge, but you said 50-60,000 ago we have split apart, how do you know that? It is a rough estimate based on the initial spread of humans from Africa - the last time the two populations had a common ancestor was when we reached the Middle East. For example, see...

Re: pairwise alignment results.I need help understanding it pls

i tried to use blastn to align the two sequences of you give, but i find the result is two bad, so i don't think you can get what u want.

i have a problem: does anybody know the '-dust' option meaning in ncbi-blast-2.2.25+/bin/blastn
