Free Genetics Flashcards
From Mendel’s peas to modern genomics, genetics runs on precise vocabulary — allele, genotype, phenotype — and a handful of ratios. Make the terms automatic and the Punnett squares solve themselves.

Reading answers is recognition — remembering them next month takes spaced repetition. Build your own genetics deck and we'll schedule every review at the right moment.

- One fact per card. Write contrast cards for confusable pairs: genotype vs phenotype, dominant vs recessive, mitosis vs meiosis.
- Rate honestly. After each card, choose Again, Hard, Good, or Easy — the spaced repetition algorithm uses your answer to decide when the card returns, right before you'd forget it.
- A few minutes daily beats marathons. Ten new cards a day is roughly 3,650 a year, retained. Deep dives: How to make flashcards that actually work · How to study for exams with flashcards.
