The researcher should conclude from her results in her phylogenetic study of organisms using geneA that "GeneA has undergone a gene duplication in several species". The correct answer is B.
A researcher is investigating how species evolved from one another using GeneA. Three different but similar gene sequences from a number of the species she is studying were obtained using the same primers. GeneA has experienced gene duplication in several species.
Those shared genes show that all life on Earth is connected and that it evolved from a common ancestor. Genes that are shared across species or even within species are referred to as homologous genes, or sometimes shared genes.
Horizontal gene transfer, or HGT, is the introduction of genetic information from one species to another through methods other than vertical transmission from parent(s) to offspring. Even organisms that seem to be phylogenetically unrelated could exchange genes as a result of these transfers.
