Simple Punnett Square Simulation
Parents with Two Alleles

This simulation randomly combines alleles from heterozygous parents and compiles a tally of the genetic make-up (genotype) of their offspring.

You can single-step the creation of offspring or auto-repeat the process at two offspring a second. (In fact you can make offspring faster by furiously clicking the “Single Offspring” button.)
