The HAPPY map of C. parvum. Chromosomes are numbered I (smallest) to VIII (largest). Second-rate markers are prefixed by 2. Those markers assigned to Cryptosporidium electrophoretic bands are labeled with an asterisk (*). Markers assigned by Caccio et al. (1998) to specific chromosomes are labeled with a dagger (†). Markers assigned in this study to specific chromosomes by the method of Caccio et al. (Fig. 3) are labeled with a double dagger (‡). Markers linked by dotted lines are linked on panel Cri4 only (lod ≤ 2 on panel Cri1); therefore; these distance estimates are less accurate. The gap marked by an arrow on chromosome VIII is not closed rigorously (lod of 1.47 on panel Cri4, probability of linkage >30:1). Chromosome V is made up of two small linkage groups, the larger of which can be orientated (see Results). Groups of markers that cannot be orientated with respect to their neighbors at odds >1000:1 are bracketed (in all cases these groups are still orientated with respect to their neighbors with odds > 5:1, and the order within such brackets is established). The position of the PAC contig (Fig. 4) is marked by a solid bar.
