The breakthrough of Mendelian genetics solved many puzzles for biologists. Then, scientists decided to apply the theory to human behavior. Learn the story and struggle of finding a genetic explanation for hobbies, interests, and mental...

Ninth graders complete a monohybrid cross and a dihybrid cross. In this biology instructional activity, 9th graders predict the traits of offspring using the Punnett square. They differentiate recessive and dominant genes.

Students, in groups, research, analyze and synthesize information on genetic diseases. After watching a video on genetics, groups perform research on a variety of genetic diseases and present their findings to the class.

Students analyze genetic characteristics in a given family tree through the F2 generation. Students apply prior knowledge from Gregor Mendel's study with pea plants and his Laws of Heredity to answer questions.

Eighth graders investigate the concept of nature versus nurture in human development through this series of lessons.
