Pure Leu Lines?

Pure Leu Lines? - 07/01/15 10:53 PM

Was wondering if we needed to keep leu lines pure anymore?

I have a male that I'm looking to pair up from my retired breeding pair and I was going to continue to keep the line pure but do we need to?

Where can I find more information on this? Lol

Thanks! =)

Pure is pretty vague, please expand your thoughts and desired outcomes?

My line doesn't have any color in it. There's no plat, no cremino's no anything.

I don't know the best course of action. I want to produce leu's and still contribute to the gene pool in a positive way.

My question is would it benefit the line to add color to it? Or leave it 100% pure?

My next question is.. I found a line that would be compatible but there's a cremino het 6 generations back. Does this matter?

I've never fretted this much over pairing a glider before. LOL

It is my understanding that if you take a standard grey with no leu in the lineage and take a Leu you have a 50 percent chance of producing a leu.

I am not sure what you want to produce.

If I had a grey with no het for anything I would find another compatible grey with no het for anything to breed it to.

In my opinion we are losing the grey lines that have no het in them.

To produce a Leu - BOTH parents must carry the recessive gene for the leucistic coloring and pass that gene on to the offspring.

Breeding a standard grey with a Leucistic glider would produce ONLY grey gliders that are 100% leu Het. All joeys would carry 1 copy of the recessive gene from the leucistic parent.

The Het stands for heterozygos meaning the glider carries 1 recessive gene for the trait - which it can pass on to its off spring.

Breeding two UNRELATED grey gliders that are both 100% leu het will produce a Leucistic joey 25% of the time. The other joeys would be standard grey and be identified as 50% Leu het because they may or may not carry the recessive gene.

There are only 3 initial leucistic glider lines. It is always best to check lineage when breeding any glider with leucistic genes to ensure the pair are not related any closer than 3 generations back in their ancestry. There is always a chance that two leucistic gliders will be related more closely and should not be paired for breeding.
