The horse breeder calculates that crossing two heterozygous palomino horses should produce 25% chestnut foals, 50% palomino foals, and 25% cremello foals. After analyzing 100 offspring, she observes 26 chestnut, 48 palomino, and 26 cremello. How should she interpret these results?
Question 5 options:
The slight variation means the traits don't follow Mendel's laws
She should expect exactly 25:50:25 in every group of 100 horses
The observed results closely match predictions, supporting her genetic model
The results prove her genetic model is completely wrong

The observed results closely match predictions, supporting her genetic model.
Reason: the counts (26, 48, 26) are very close to the expected (25, 50, 25). A chi-square test gives χ² = 0.16 (df = 2), far below the critical value (≈5.99), so the deviation is not statistically significant — consistent with random sampling variation.
