Working in pairs, students will select one human trait and demonstrate three generations on a Punnett Square. Individual groups will write their results on the chalkboard. Then each group will discuss the accuracy of their results. Students will write a paragraph explaining how inheritance of dominant and recessive genes helps produce variation in a population. Dominant and recessive genes can contribute to variation in a species.
Variation is necessary for the survival of a species.
