Two parents, a punnett square in your head, call the offspring odds, then hatch.
Was this fun?
How to play
You're shown two parent creatures with known genotypes for a trait. Predict the probability of each offspring outcome, effectively reading the punnett square, place your bet, then hatch the offspring to see if your ratios were right.
Read both parents' genotypes for the trait in play
Bet the probability of each possible offspring result
Hatch to reveal the outcomes against your prediction

Tips & strategy
Sketch the punnett square: each parent contributes one allele per offspring
A heterozygous cross often gives the classic 3:1 dominant-to-recessive split
Two heterozygous parents yield 1:2:1 across the genotypes, lean on those ratios
What you'll learn
Punnett is a genetics game about inheritance, working allele crosses and the probabilities that decide which traits appear.
