Final answer:
A coefficient of coincidence value of 1.0 obtained from a three-point linkage analysis indicates that there were no observed double crossovers in the progeny.
Step-by-step explanation:
The coefficient of coincidence value of 1.0 obtained from a three-point linkage analysis indicates that all observed double crossovers were completely coincident. In other words, there were no observed double crossovers in the progeny. A coefficient of coincidence value of 1.0 means that all expected double crossovers were successfully suppressed and only single crossovers occurred in the progeny.
