Genes that have been derived from a duplication following transfer; ^†transferred genes that have less support. GenBank accession numbers are as indicated. Locations are given as chromosome number. The expression status for each gene is indicated by method: EST, RT-PCR or assay. Only 567 EST sequences exist for C. parvum. A + in the indel colum indicates the presence of a shared insertion/deletion between the C. parvum* sequence and other sequences from organisms identified in the putative origin column.
