General Biology I (BIOL 101) Genetics: Punnett Squares and Hardy-Weinberg Practice Problems
University of California, Los Angeles
General Biology I (BIOL 101) | Practice Problems

Overview
A practice packet on Mendelian genetics, probability, and population genetics setups that students see on exams.

Key topics
•monohybrid and dihybrid crosses
•probability and inheritance
•pedigrees and carriers
•Hardy-Weinberg setup and interpretation

Suggested study tasks
•solve 6 Punnett square word problems
•translate a pedigree into genotypes
•compute allele frequencies from counts
•explain what p and q mean in a scenario

Common pitfalls
•mixing genotype and phenotype ratios
•forgetting independent assortment in dihybrid crosses
•using p+q=2 instead of 1
•assuming Hardy-Weinberg always applies without conditions
