Square Worksheet With Answers
AboutTranscript. Punnett squares help predict offspring traits by showing possible gene combinations from parents. In addition, Punnett squares can illustrate trends among dominant and recessive traits, incomplete dominance, codominance, and dihybrid crosses. Punnett squares are useful for understanding genetics and inheritance patterns.

Each genotype shown in the Punnett Square has a 25% chance of occuring. If the same genotype appears in more than one square, the probabilites are added: 1 square = 25% probability 2 squares = 50% probability 3 squares = 75% probability If the same genetype appears in all 4 boxes, 100% of the offspring will have that genotype.
