A researcher is conducting a phylogenetic study of organisms using GeneA. In several of the species she is examining, she retrieves three different but similar gene sequences using the same primers. What should she conclude from her results?
-She has contamination in her experiments and should start over.
-GeneA has undergone a gene duplication in several species.
-GeneA is currently evolving in those species she found different sequences. It will be found as a different sequence in different tissues.
-GeneA has different alleles in some species.
-It is impossible to tell from the given information.
