As a part of a phylogenetic study, I need to find a nuclear gene that meets the following requirements:
- Single copy gene;
- Highly variable gene;
- Gene longer than 400 bps;
- Gene that gives information at the species/genus level in Gastropoda.
My candidate genes are the following: 5.8S, 18S, 28S, ACT, APN54, EF-1alpha, endo-1,4-beta-glucanase, GSTM, GSTO, GSTP, H3, ITS1, ITS2, MCP, MYO.
However, I do not know where to find whether or not they are single copy.
