Ksenia Semina Evolution Lab ARR 3 Blast Lab Analysis: Gene 1: The 4 organisms that were looked at in the Gene 1 are bird‚ vertebrate‚ rodent and bony fish. From the Blast result the most similar gene sequence to the gene of the gene of interest is Gallus gallus collaged which is also a bird. They are the most similar because the Gallus has the highest max score out of all other genes and 100% for the ident and there is no difference in the e-value. The species is located at the bird’s branch
