To determine the genotype of parent 2 based on Mendel’s laws and the Punnett square, we need to know the offspring ratios produced from the crossing of the two parents.

If you have a Punnett square indicating the genotypes of the offspring, it can help us infer the genotype of parent 2.

1. If the offspring show a 3:1 ratio of dominant to recessive traits, parent 2 is likely homozygous dominant (FF).
2. If the offspring show a 1:1 ratio, parent 2 is likely heterozygous (Ff).
3. If all offspring are dominant and none are recessive, parent 2 is also likely homozygous dominant (FF).
4. If the offspring show a 9:3:3:1 ratio, a dihybrid cross indicates parental genotypes are likely Ff for both parents.

Without the exact offspring ratios from the Punnett square, we can’t provide a definitive answer. I recommend checking the information within the square for ratios to determine the genotype more accurately.

If you have further context or details from the Punnett square, feel free to share!
