I have made 4 gene disruptions in K.lactis. 2 were easy, 2 were more
difficult. From what I gather there seems to be a locus specific
effect, but there are also other things that have an effect. But I
don't know what they are. Frequencies are generally low (similar to
yours), but sometimes for some reason or other frequencies are much
