Multiple copies of zferv are present in the zebrafish genome. (A) Diagram of the original zferv genes found by Shen and Steiner (2004) used as a reference for nucleotide identity (ID% nt). (B) Diagram representing the two closest related zferv genes found in most recent zebrafish genome GRCz11, named zferv1a and zferv1b. (C) Diagram of six pseudo zferv genes with degenerated genome (dashed line represents insertions). 3′LTR, 3′ long terminal repeat; 5′LTR, 5′ long terminal repeat; env, envelope gene; gag-pol, genes encoding polyprotein and reverse transcriptase; Rep., repetitive element.
