Hard to tell, but I'm almost certain they are red-eared sliders. They have color patterns that are abnormal. I've seen them labeled as "pastel" or "clown". I haven't been able to get a solid answer, but I think this is a developmental abnormality... often associated with other physical defects such as scute duplication... not a genetic trait like albinism. Thus, I don't think they would produce similarly colored offspring. I may be wrong, and I hope someone can clarify.
