7.“Remember the appearance”. (Case-lesson “Mutational variability”)

The essence of the task: Break into pairs and watch each other for 10 seconds. Now turn away and tell what the color of the eyes of your “Vis-à-vis” was. What was the shape of their nose, hair color? Is there a dimple on the cheek or chin? Is their hair smooth or wavy? So, who is more attentive in your pair? Do you know which of these features are recessive and which are dominant? Which of them are inherited and which are modified?

OBJECTIVE: Train attention, give an idea of hereditary characteristics, which are displayed in appearance, mobilize children and set up friendly, positive mood.
