  • a From Endo and Gill (1996).

  • b Determined from arm ratio value (Gill et al. 1991) for arms and from the physical length of the bin for bins.

  • c Ratio of observed to expected number of loci.

  • d Test for probability of departure of observed from expected number of loci.

  • e A total of 965 EST loci mapped to chromosome arms generated from only those ESTs having all restriction fragments mapped.

  • f A total of 854 EST loci mapped to chromosome bins generated from only those ESTs having all restriction fragments mapped.

  • *, **, and ***, significant at 0.05, 0.01, and 0.001 probability levels, respectively.
