Biology Unit 10: Heredity
9 topics · Start with Asexual Reproduction
This unit follows traits from parents to offspring. You’ll compare asexual and sexual reproduction, see how meiosis makes gametes, predict the results of crosses with Punnett squares and pedigrees, and learn how scientists copy, sort, and change DNA.
Study Tips for Unit 10
- Practice Punnett squares by hand until setting one up feels automatic, and write each probability as a fraction.
- For every pedigree, write the genotypes you can work out before you calculate anything.
- When you see a ratio from a cross, ask which pattern it matches: 3 : 1 (complete dominance) or 1 : 2 : 1 (incomplete dominance or codominance).
Unit 10 Study Guide
A printable review of all 9 topics, with an answer key, is coming soon. Until then, use the practice worksheet at the end of each lesson.
