post below made me wonder......

I'm sure it's been done many times due to their commonality, but does anyone know with certainty if breeding a ruby eyed Lav with a common albino coastal yields double hets (2 incompatible genes) or a blended shade of albino (same)

Since lavender and albino are 2 separate recessive genes......the offspring will be "normal" but double hets (lavender & albino).

But sometimes when breeding 2 recessive genes together the babies can appear "other than normal".

That's what I'm anxious to see. I'm expecting normals with some abberant/striped patterns. I'm wondering IF the lavender is actually a T pos what would come of breeding the double hets? What would a snake with both T pos and T neg genetics look like? Have you done this?

Ok, I'm guessing a snake with both t pos and t neg genes would appear as a t neg, unless somehow the t pos would be dominant?

Amy won't it be invisible since they cancel each other out? Just kidding, I asked the same thing about Florida Kings once but didn't really get an answer. Your probably right though that it would be hard to tell them apart, if one masks the other.

It would probably be like a hybino in kingsnakes. The T- cancels out the T or the hypo gene and looks like a normal T- albino. IMO, the only thing cool that comes out of that pairing (lavender X albino), is the hets can look hypo.

I meant to say...The T- cancels out the T (positive)

Yeah, Im pretty sure that is what would happen. Well, first we have to see if she lays any eggs!

Ha ha, yeah, I was wondering if they might be clear, lol.

It is typically be the other way around Amy. Morphs that are also homozygous for the t-negative form of albinism would typically be visually displayed as such. It's just like a hybino Honduran (hypo x t-neg. amel) where they look like typical amels but are also homozygous for hypomelanism. It wouldn't matter if the gene came from very dark hypos or outstanding extreme hypos, they would still look like typical amels because the amelanism "masks" the other genes that involve melanin.

Now sometimes mixing different morphs and phenotypes can produce some different looks, but it isn't always necessarily from the other recessive gene alone itself. There can be countless unknown factors.

.....sorry Amy, I misread your sentence and thought you meant t-pos, not t-neg...LOL!.......so basically you were correct. As specified, the tyrosinaise would typically be masked by the amalanism (complete lack of all melanin as well as the copper containing tyrosinaise that synthesizes it)

Ha ha, thanks, Doug, and sometimes I talk backwards so its easy to misunderstand me.

So basically, if I bred the double hets and got normal albinos, I wouldnt be able to tell if they were also t pos. Right? That is, if that is what the lavender is.

From what I've heard, yeah, you are right.
-----

Yes, that's right. You would later have to produce a visual lavender/t-positive offspring from those double hets. Then when that particular snake produces ANY typical amel "looking" offspring when bred back to any of it's double het sibling clutchmates, these would automatically be 100% known double homozygous animals for both traits..

Doug, that's because you are still thinking about the T pos. in L.t.nelsoni which seems to be dominate over T neg....Things that make you scratch your head! LOL
-----

Well, in this particular case I simply confused the two terms in my head as I was typing..LOL!

But yeah, the t-plus nelsoni mode of inheritance is quite odd to say the least..

In 2006 I bred my 1.3 double hets together (albino & lavender).

Here is a link to the results.

Very cool, Kerby. It totally slipped my mind the double homo would be 1 in 16. Maybe no way in telling anyway.

Love the different shades of colors going on with those babies!!

So I could get an assortment, even with the original double hets, since I don't know anything about their parent's genetics. I sure hope she lays some eggs!

Man, I really enjoyed looking at your pics! THanks again.

What ever came of the purple passion? Any adult pics? And what's different about the lavender male -JR?
