السؤال 70

A class crosses many heterozygous pea plants and compares the seedlings they count with the predicted 3 to 1 ratio. Which statements about that comparison are true? Select all that apply.

Counting a large number of seedlings usually gives a closer match to the predictionالإجابة الصحيحة
Counting more seedlings pushes the results further from the prediction
Small groups of seedlings vary noticeably from one group to the nextالإجابة الصحيحة
A group of seedlings that does not match exactly shows the prediction is wrong

الشرح

Chance evens out as the count grows, so the proportions in a large batch sit close to the predicted ones while a handful of seedlings can land almost anywhere. Treating a mismatch in a small group as evidence against the prediction confuses ordinary scatter between small samples with a fault in the prediction itself.
