The teacher gives the students the following order: “Which member of your family can roll her/his tongue and who can’t? Write it down!” The answers should be entered in the table. In addition, this order can be given as homework.
Can roll her/his tongue | Can’t roll her/his tongue |
---|---|
The task should explain the inheritance of a phenotypic trait.
Besides, the teacher can adapt the task to the abilities of the students: If the children are familiar with it, they could draw a family tree. Or it can be introduced as a new concept and the students could edit it at school.
