Morph Crossing Questions

[cat_named_noodles]

OK, this is a question for breeders or any one interested in leo genetics. If Finn (my Mack snow possibly with eclipse,Tremper albino, and stripe lines) is indeed a boy, then I want to know, what morphs I could get breeding him to the following:
1.Neko- Patternless Stripe (also poss. eclipse, Tremper)
2.Athena- Aberrant; possible reverse stripe (don't know what her original tail looked like)
3.Sprocket- SHTB (most likely SHTCTB)

If Finn turns out to be a Flower, then I will likely consider getting a RAPTOR, APTOR, or Mack Snow Enigma. Anybody have any ideas what that group might produce?
Thanks!

If finn is only a mack snow then x patternless stripe would be 25% Normal het Patternless, 25% Stripe, 25% Mack snow stripe, and 25% Mack snow het Patternless. Finn x Aberrant would be some aberrants, some Mack snows, and some inbetween. finn x SHTCTB would be the same getting some Mack snows with a little bit of orange color on the tail.

I'm not going to try to figure out all the possibilities, but here are some guidelines to help you figure it out on your own.

There are 3 different kinds of genes to take into account with these crosses:

1. Simple recessive: 1 copy of the gene will not show up visibly and would make the animal het; 2 copies of the gene will show the recessive trait. Both parents need at least 1 copy of the gene for there to be any chance of the babies to show the trait. The only simple recessive in your combinations is the albino, although I don't know enough about the eclipse to know if that works in this category or not

2. co-dominance/incomplete dominance (the jury seems to be still out on this one and I'm not even going to venture a guess): a gecko with 2 copies of the gene will have a specific, non-"normal" appearance (e.g. super snow) and with 1 copy of the gene will have a different non-"normal" appearance (like a regular Mack snow). So, you only need 1 parent with a copy of the gene to have a chance of offspring with a copy of the gene, but to get the super, 2-gene form, you need both parents to have at least 1 copy of the gene each.

3. Line bred: these characteristics show up in varying degrees, and tend to show up more when you breed 2 geckos that both have the characteristic. In other words, 2 stripes bred together will have more striped offspring than a striped and a banded. Most likely, all the other characteristics you mention are in this category (stripe, super-hypo, etc), although it is not clear exactly how the stripe genes work.

So, you should be able to figure out the albino and Mack snow part. The best chances of stripes would be by pairing stripes (including reverse, patternless stripes, aberrants), and everything else should appear on a continuum from strongly visible, to not much.

I hope this is helpful.
