Genetics
Explore the core ideas of genetics, from DNA and genes to inheritance patterns and variation. These quizzes help you review key terms, interpret simple genetic scenarios, and connect molecular processes to traits and evolution.
Quizzes
Mendelian inheritance: monohybrid and dihybrid crosses
Test your genetics fundamentals with monohybrid and dihybrid crosses, from simple dominance to classic Mendelian ratios. Work through Punnett squares, genotype/phenotype predictions, and probability questions with a balanced mix of easy, medium, and challenge items.
Gene expression: transcription and translation basics
Test your understanding of how cells turn DNA instructions into functional proteins. This quiz covers the core steps of transcription and translation, key molecules involved, and classic gene-expression terminology. Expect a mixed set of questions that builds from fundamentals to common exam-style scenarios.
DNA replication: enzymes and proofreading
Test your understanding of DNA replication with a focus on the enzymes that drive the process and the proofreading that keeps genomes accurate. You’ll cover helicase, primase, DNA polymerases, ligase, topoisomerases, sliding clamps, and mismatch repair. Mixed difficulty makes it useful for quick revision or deeper practice.

Quick genetics context
Modern genetics grew from Mendel’s pea plant experiments, but it expanded rapidly once DNA was identified as the hereditary material and the double-helix structure explained how genetic information can be copied.
