Fig. 5.
Recombinant sequences resulting from cloning of PCR products containing mixtures of C. parvum (GenBank accession number AF164102) and C. andersoni (GenBank accession number AB089285). Shaded areas indicate regions homologous to C. andersoni, while unshaded areas indicate homology to C. parvum. Circled bases indicate sites of random single-nucleotide polymorphisms. (a) Nucleotide positions 324 to 523 of C. parvum (accession number AF164102). (b) Nucleotide positions 624 to 860 of C. parvum (accession number AF164102). Positions 524 to 623 show no sequence variation between C. parvum and C. andersoni.
