  • Classifiable tetrads, drawn from the following numbers of four-spore-viable tetrads: Petes MSH4, 3037; Petes msh4, 1596; Rine MSH4, 2876; Rine msh4, 1424. Percentages are of classifiable tetrads. Crossovers are TT + NPD. Noncrossovers are PD. CO, crossovers; NCO, noncrossovers.

  • a Two-tail probability that the difference between the two independent proportions could be due to chance alone.
