Question 2 1 points Save A 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 se, so he performed a chi squared goodness of fit test and calculated x2-0.237, If only two phenotypes were Table3.4 Critical values of the x* distributiorn possible, can he reject the null hypothesis?9 7 0.000 60000016 045 2.706 3841 5.024 6435 789 6073 0.216.5842.6 1 9.34 11.345 1 o Yes.

Explanation / Answer

Df = 1 since only 2 phenotypes are there.

Chi sq critical value = 3.841

Since Chi sq < Chi sq critical, we fail to reject Ho.

P-value - 0.6264

Answer - No, P > 0.05 so any difference since was due to chance
