Think of your own family, what similarities do you share with your father and mother? Draw a table to represent the similarities of some characters like colour of eye (cornea), colour of hair, shape of nose, shape of face, type of earlobe (attached or free) inner thumb markings, etc. Write your characters in one column and that of your parents in the other columns.
(Q) . is there any character that is not present in grandma but present in your mother and you ?
