- 10. The first and fourth Punnett squares are correct.
- 11. The letters on the outside represent the alleles contributed by each parent.
- 12. The letters on the inside represent the possible genotypes of the offspring.

- Square 1 (NN x nn): All four boxes are Nn. Put an X through all four.
- Square 2 (Nn x NN): Top row is NN, NN; bottom row is Nn, Nn. Circle the top two (NN), put an X through the bottom two (Nn).
- Square 3 (Nn x Nn): Top row is NN, Nn; bottom row is Nn, nn. Circle the top-left box (NN), put an X through the other three (Nn, Nn, nn).
- Square 4 (Nn x nn): Top row is Nn, nn; bottom row is Nn, nn. Put an X through the two Nn boxes, leave the two nn boxes unshaded.
Parent Tip: Review the logic above to help your child master the concept of punnett square worksheet with answers.
