When I first saw that you couldn't impregnate Kaska at Gastigoth, I thought that it had something do to with her being an alpha dzaan and thought she couldn't get pregnant for biological reasons. Just now when I was skimming through the codex I noticed that while an alpha dzaan hasn't been recorded to have impregnated another alpha, they have been recorded to be impregnated by humans and ausurs and other similar species. My question being, Is there a specific reason why you can't impregante Kaska?
