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.

This is the a complete excel workbook with all learning objectives for the OCR A Level Biology A Specification. Each topic has its own tab, the first spreadsheet hyperlinks to each topic as needed (and hyperlink back to table of contents (TOC) and the layout has been set ready for printing, with some topics that take up two pages having the headings ready to go on both. Please leave a review and check out my other items.
