General Biology I (BIOL 101) Genetics & Punnett Squares Practice Problems
University of California, Los Angeles
General Biology I (BIOL 101) | Practice Problems

Overview
A practice packet on Mendelian genetics, test crosses, non-Mendelian patterns, and probability so you can solve exam-style inheritance questions quickly.

Key topics
•Mendelian inheritance patterns
•Punnett squares and probability
•test crosses and pedigree basics
•non-Mendelian inheritance (incomplete dominance, codominance, sex-linked)

Suggested study tasks
•solve 8 Punnett-square problems with probability
•identify pattern type from a short prompt
•work one pedigree question and justify the mode of inheritance

Common pitfalls
•mixing genotype and phenotype language
•forgetting to multiply independent probabilities
•misreading sex-linked inheritance in pedigrees
