Question 8: In majority of analyses, an alpha of 0.05 is used as the cut-off p-value for the chi-square analysis .
Therefore, correct option is (0.05)
Question 9: for dihybrid cross,
degree of freedom = number of phenotypes - 1
= 4 - 1
= 3
(Since, in dyhybrid cross, we expect to see 4 different types of phenotypes)
Therefore, the correct ans is (3)
