  • Calculations are based on the data of Table 7. “Combined data” refers to the combined data from the msh4 and MSH4 crosses.

  • a Source for all values except the 6:2 Msh4-independent crossovers.

  • b Combining the data deals with the slight msh4-induced shift of 5:3 crossovers into the 5:3 noncrossover class.

  • c Fraction of noncrossover conversions that are 6:2.

  • d Fraction of Msh4-independent conversion crossovers that are 6:2.
