Answer / jomy peter thomas
just do blastn and count the number of sequences showing
more than equal to 30% similarity with the known sequences
in the databases.this wud give u th no. of homologous sequences.

Answer / guest

Suppose the Blast search returned 100 hits. Of these, 17 were false positives and we knew that there were 165 sequences in the database which should have returned a hit with our sequence. How many false negatives were there, and what is the sensitivity and selectivity of Blast in this instance?
