Summary
A three-point cross in the b2 locus of Ascobolus immersus was devised in such a way that asci showing independent correction tracts within the same length of heteroduplex could be selected. The occurrence of independent corrections was confirmed. The calculation is compatible with the idea that the distances between the markers used was often, and perhaps always, in excess of the length of the correction tracts.
