Use a Punnett square to determine the probability of one of their offspring having long hair. A) 100%: B) 25%: C) 75%: D) 50%: 2: One cat carries heterozygous, long-haired traits (Ss), and its mate carries homozygous short-haired traits (ss). Use a Punnett square to determine the probability of one of their offspring having short hair.

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.

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.

Square Practice Worksheet Answers
If we look at our Punnett square, we find that there is a 1/4 chance of offspring being homozygous dominant for smooth kernels (KK) and a 2/4 chance of that the offspring will be heterozygous (Kk) for smooth kernels. Combined, we find that there is a 3/4 chance that the offspring will have smooth kernels. The correct answer is. 3/4
