  1. * Proportion of marker pairs that X2 exceeded 3.84, the 5% critical value of χ ( 1 ) 2 .
  2. a The chromosome length was shorter than 50 Mb and there were no marker pairs with a distance that would exceed 50 Mb.
  3. b Chromosome 26 was 52 Mb long but no marker pairs with a distance of >50 Mb had a chi-square statistic that exceeded 3.84.
