A Researcher Has Sequenced a Gene from Four Populations of an Organism,denoted

A researcher has sequenced a gene from four populations of an organism,denoted 1,2,3,and 4.This gene consists of two exons separated by an intron; a 5¢ untranslated region (UTR)is included in the first exon,and a 3¢ UTR is included in the second exon.When we align the four sequences of this gene,we find that two of them have a transposable element insertion in the 3¢ UTR,and three of them have lost a short sequence within the intron.We also see that each of the four sequences has at least one feature that uniquely distinguishes it from all the other sequences-a G:C base pair near the start of the coding sequence in exon I in sequence 1,an A:T base pair near the start of exon II in sequence 2,a C:G base pair in the 5¢ UTR and a T:A base pair near the end of the coding sequence in exon II in sequence 3,and an A:T base pair in the 5¢ UTR,a C:G base pair in the middle of exon II,and a G:C base pair in the 3¢ UTR in sequence 4.Based on these similarities and differences,draw a phylogenetic tree to show how the four sequences are related.
