Genetics and Inheritance Punnett Square Simulation

Science · Genetics and Inheritance · Middle School and High School

About this simulation

In Mendelian inheritance, offspring receive one allele from each parent. Genotype combinations determine phenotype probabilities according to the chosen dominance pattern. Students can change parent 1 genotype and parent 2 genotype and compare what happens. Use it for biology inquiry with Middle School and High School on a projector or student device.

Standards: NGSS MS-LS3-2

What students can explore

Build all four allele combinations in a Punnett square
Compare homozygous and heterozygous parent crosses
Distinguish genotype probabilities from phenotype probabilities

Learning objectives

1Predict how changing parent 1 genotype will affect the dominant phenotype, then test the prediction.
2Use evidence from the interactive visual to explain the result.
