By winnowing down possible regions of the elephant genome that may contain the genes for tusklessness, the team narrowed their focus to the gene 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 hard tissue that supports and anchors teeth. the questions from the Task 1 handout.
