10. First and fourth Punnett squares are correct
11. Parental alleles (gametes)
12. Offspring genotypes
13.
- First square (N × N, n × n): all offspring = Nn → circle none (no homozygous dominant), X all four (all heterozygous), leave none unshaded (no homozygous recessive)
- Second square (N × n, N × n): offspring = NN, Nn, Nn, nn → circle NN (homozygous dominant), X Nn and Nn (heterozygous), leave nn unshaded (homozygous recessive)
- Third square (N × n, n × n): offspring = Nn, Nn, nn, nn → circle none, X Nn and Nn, leave nn and nn unshaded
- Fourth square (n × n, n × n): all offspring = nn → circle none, X none, leave all four unshaded
Parent Tip: Review the logic above to help your child master the concept of punnett square practice worksheet.
