12 In a sample of newly hatched beetles 26 7 had bright red spots on their wings and 73 3 had dull red spots You hypothesize that this ratio is 1 3 and is the product of a monohybrid cross a These proportions could be validly compared to the predicted proportions using a Chi square test b More information about the parents is needed before a hypothesis can be developed c The prediction cannot be tested with a Chi square analysis of these numbers d A monohybrid produces a 3 1 ratio not a 1 3 ratio so the hypothesis is wrong 13 Assume you are doing a Chi square test on the phenotypes that result from a dihybrid testcross How many degrees of freedom would there be a 1 b 2 c 3 d 4 e This is America so all the degrees are free
