This 25 page activity sheet is all about M&Ms genetics. Topics covered in this activity are: dominate, recessive, incomplete dominate, pleiotropy, co-dominate, dihybrid cross, Law of Segregation and Law of Independent Assortment. Worksheets with all of the genetics and punnett squares are included with 6 listed crosses for students to complete, and 2 dihybrid crosses. Also I included blank punnett squares and dihybrid squares for you to make your own crosses. At the end of the activity there are three questions extension. If you wish for a quick assessment as well there is a 10 question quiz based on the activity and there is a teacher key included with answers for everything! I have separated the dihybrid pletropic section to make this easier for use from 7th grade to 11th grade.
