I created this worksheet as a support sheet for students struggling with drawing Punnett squares in the genetics topic. This worksheet is best printed off on A3 and works to walk students through the steps involved in determining the alleles of the parents and creating a Punnett square to determine the probability of certain outcomes. The layout is in a style that allows students to easily follow the process. Have used a similiar format in the past on calculation style questions in physics and drawing ionic bonds in chemistry and students loved it! I have also included the answer sheet to go with it.
