To suggest rule for inheritance of earlobe type. Procedure /Method : rarr The lowest part of the ear pinna called the earlobe, is closely attached to the side of the head, i.e., attached or not, i.e., free. rarr Observe the earlobes of all the students in the class. Prepare a list of students. Enter the data about the earlobes whether they are free or attached. rarr Find out about the earlobes of the parents of each student in the class. rarr Correlate earlobe type of each student with that of their parents. rarr In the column write F for free earlobe and A for attached earlobe.
