Use the following to answer questions You are doing lab work with a 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 antenna. Crossing F1 progeny with beetles that have green shells and short antenna yields the following progeny: Blue shell, long antenna82 Green shell, short antenna78 Blue shell, short antenna37 Green shell, long antenna43 Total240 -Assuming that the genes are linked, what is the map distance between them in m.u.?
