Suppose you performed two BLAST searches, one on the peptide sequence FIDPWE, and another on the sequence KRTIAAVNSPLLEVATY.

Which search do you predict will give you alignments with "expect scores" closer to one? Explain your reasoning.

1. The expect score for the longer sequence is more likely to be closer to one (i. e., the longer sequence consists of greater variety of amino acids).
2. The expect score for the shorter sequence is more likely to be closer to one (i. e., the shorter sequence is more likely to match many entries in the database).
