Genetic map distances calculated from four-spore viable tetrads.

The map distances in cM between the indicated markers and the number of each tetrad type observed (as calculated by RANA software; Argueso et al.[11]) are shown. Chromosome XV data were obtained from EAY background strains; chromosome III, VII and VIII data were obtained from NHY background strains. The Stahl lab online tools (http://www.molbio.uoregon.edu/~fstahl/) were used to calculate the genetic distances and standard errors (SE). p values for G-tests comparing the tetrad type distributions for all mutant combinations were calculated using the spreadsheet available from The Online Handbook of Biological Statistics (http://udel.edu/~mcdonald/statintro.html).
