All markers are codominant except AP19 and AP4, which are dominant. AP4, AP19, and B16 are unlinked to all other markers or to each other. All others are linked (Fig. 2). Unlinked dominant RAPD markers P2 and M4 showed no changes among any zoospore lines. NC15A and NC15B are different subcultures of the same F1 individual.
