The goal of this task is for you to make a prediction about the future of these populations. By winnowing down possible regions of the elephant genome that may comprise the genes for tusklessness, the team narrowed their focus to the factor MEP1a, which codes for some aspects of teeth formation, and the X-linked gene amelogenin (AMELX), which is responsible for the biomineralization of tooth enamel and the formation of gums and cementum, a type of difficult tissue that supports and anchors teeth. . a.
