Only four-viable-spore tetrads were analyzed. For HIS4 and ARG4, gene conversions were scored as tetrads exhibiting 3+:1 or 3:1+ segregation for the marker. For LEU2, the presence of a Leu+ spore indicated gene conversion. Numbers in parentheses indicate the number of tetrads assayed.

  • a The data for NH144 and NH274 are taken from de los Santos et al. (2001).

  • b This value is statistically significantly different from wild type (P < 0.05). Statistical analyses were performed using programs at the following websites: map distance, http://groik.com/stahl/; gene conversion, http://faculty.Vassar.
