AP Bio Pedigree Practice Cheat Sheet
- Understand pedigree chart symbols - Master the language of pedigree charts by learning that squares are males, circles are females, and shaded shapes indicate affected individuals. Think of these symbols as the secret code that unlocks any family mystery. Pedigree Analysis Basics Pedigree Analysis Basics
- Recognize autosomal dominant patterns - Traits that pop up in every generation and never skip a beat usually follow an autosomal dominant pattern. If you see each affected child with at least one affected parent, you've cracked the code. Autosomal Dominance Primer Autosomal Dominance Primer
- Identify autosomal recessive inheritance - When traits hide for a generation before reappearing, you're likely dealing with autosomal recessive inheritance. Unaffected carriers can pass on the hidden allele, making this pattern a sneaky one. Autosomal Recessive Insights Autosomal Recessive Insights
- Distinguish X‑linked dominant inheritance - In this pattern, affected fathers transmit the trait to all daughters but no sons, while affected mothers can pass it to both sons and daughters. Spotting this trend helps you predict inheritance with laser focus. X‑Linked Dominant Guide X‑Linked Dominant Guide
- Recognize X‑linked recessive inheritance - More males than females show symptoms, and affected fathers never give the trait to sons but can make their daughters carriers. Watch for skipped generations and "carrier moms" passing it to sons. X‑Linked Recessive Guide X‑Linked Recessive Guide
- Understand mitochondrial inheritance - Mitochondrial traits come exclusively from mom, so every child of an affected mother will show the trait, but none of her children's fathers will pass it on. It's the ultimate maternal legacy. Mitochondrial Inheritance Explained Mitochondrial Inheritance Explained
- Practice analyzing pedigrees - The more family trees you dissect, the sharper your inheritance-pattern radar becomes. Grab real-life examples, annotate them, and quiz yourself to boost confidence. Pedigree Practice Pedigree Practice
- Learn to construct Punnett squares - Punnett squares turn abstract alleles into visual grids showing all possible offspring genotypes and phenotypes. It's like playing genetic bingo with guaranteed insights. Punnett Square Practice Punnett Square Practice
- Be aware of Mendelian exceptions - Not all traits follow simple rules: incomplete penetrance can hide a trait, and variable expressivity can change how it shows up. These twists make pedigree puzzles extra spicy. Mendelian Exceptions Mendelian Exceptions
- Engage in team‑based learning - Collaborating with classmates on pedigree problems turns studying into a game of genetic detective work. Two brains are better than one for spotting patterns and swapping "aha!" moments. Team‑Based Learning Article Team‑Based Learning Article
