I need a genetic calculator for rtb's lol. I haven't found one. The one for balls is awesome. Made it sooo much easier to learn my morphs that way. I just got back into boas this year. I had a female Suriname and a hypo colombian male that I bred in 99 and 00. Then I got divorced and she took them. I had no clue about genetics at all back then. I was selling them to pet shops 10 for $300 lol.
