Model: separate sexes with non-overlapping generations. Each generation: gametes form and mutate (A to a at rate μ, a to A at rate ν), a fraction m is replaced by migrant genes from a source population, gametes unite with inbreeding coefficient F (genotypes p²(1 − F) + pF and so on), zygotes survive in proportion to their fitness w, and Nm males and Nf females are drawn at random from the survivors (genetic drift). Mutation rates are set far above real rates (about 10−5) so their effect shows within 150 generations. Each panel shows up to 24 individuals; for larger populations they are a sample in the right proportions.
Problems are randomly generated. Type frequencies as a decimal (0.04), a percent (4%), a fraction (1/16) or "1 in 25"; very small numbers can be typed as 2e-5 or 2 x 10^-5. Answers within about 2% are accepted (3% for equilibrium approximations), so rounding is fine. Each answer is also checked by a separate solver that works the problem a different way.

Drag a card onto a box, or tap a card and then tap the box's name. Cards are buttons, so Tab and Enter work too.
Teaching scenarios built on published patterns, simplified; values marked illustrative are rounded for teaching. Families and people are fictional. For learning only, not medical advice or genetic counseling.
