Yоu аre dоing lаb wоrk with а new species of beetle. You have isolated lines that breed true for either blue shells and long antenna, or green shells and short antenna. Crossing these lines yields F1 progeny with blue shells and long antennae. Crossing F1 progeny with beetles that have green shells and short antennae yields the following progeny: Blue shell, long antenna 82 Green shell, short antenna 78 Blue shell, short antenna 37 Green shell, long antenna 43 Total 240 A chi-square test is done to test for independent assortment. What is the resulting chi-square value and how many degrees (s) of freedom should be used in its interpretation?
