Unit 5 notes from Mr. W

• The tutorials and student learning guides below have been updated to align with the College Board’s 2025 Course and Exam Description.
• Because these topics involve chromosomal inheritance, we’ve moved some material from topics 5.4 and 5.5 (such as sex determination) into our tutorials about meiosis and chromosomal inheritance.
