a
Intrastock classifications were compatible (*) or incompatible (=). Interstock classifications were positive (+) with isolation of stable heterokaryons, cryptic (±) where, although junction zone interactions were observed stable heterokaryons could not be established, or incompatible (−).
b
Mating type assignments are not equivalent in different compatibility groups.
