Question

A geneticist discovered a new species of insect with variable antennae length. He performed the following cross (Bb x bb) and counted the number of offspring with different antennae lengths. He was unsure if his observations matched what he expected to see, so he performed a chi-squared goodness of fit test and calculated Х 2 = 4.03. If only two phenotypes were possible, can he reject the null hypothesis?

No. P < 0.05 so any difference seen was due to chance.

Yes. P < 0.05 so any difference seen was due to chance.

No. P > 0.05 so any difference seen was due to chance.

No. P > 0.05 so any difference seen was not due to chance.

No. P < 0.05 so any difference seen was not due to chance.

Yes. P > 0.05 so any difference seen was due to chance.

Yes. P > 0.05 so any difference seen was not due to chance.

Yes. P < 0.05 so any difference seen was not due to chance.
