Mendelian Inheritance
by Anonymous
Set the parents' genotypes and fill a Punnett square to see how dominant and recessive alleles give a 3:1 ratio, and how A, B, O genes split into four blood types.

About this app
Mendelian Inheritance is an interactive middle-school science app for exploring dominant and recessive traits. Choose individual pea genes to see how genotype determines yellow or green appearance, then use Punnett squares to model the four possible offspring combinations. A separate blood-type activity demonstrates how A, B, and O alleles produce the four blood types and how hidden O alleles can result in type O children.
Use cases
- Middle-school students learning basic genetics
- Teachers demonstrating dominant and recessive inheritance
- Families exploring Punnett square outcomes
- Learners practicing pea-trait and blood-type genotype problems
Features
- Interactive selection of Y and y genes to build pea genotypes
- Visual explanation of dominant yellow and recessive green traits
- Punnett square calculations for four offspring combinations
- Displays yellow-to-green offspring counts and ratios
- Blood-type genotype activities using A, B, and O alleles
- Challenge scenarios including type A parents having a type O child
