my current 2011 breeding plans and a question

[mechnut450]

ok I plan on breedingthis year if they will go;
my het pieds again( she gave me 6 eggs her first time and is already back to the wieght she laid at),
my butter to normals,
my pinstripe to normals,
and my albino already locking with 4thesnakelady's 100% het albino ( we agree to a 50/50 split).
but I was wondering and the more xp breeders can tell me . with my pinstripe and butter( i know can have double sired clutchs) if I toss the males in with the same females if the possible morph ratio is higher or it like everything else just chance. also what is safest the number of females you will breed a single male to ( with a couple days between pairing to rebuild his stamina)
reason I ask only got the 2 planned co-doms this year I not going to use my male pastel ( as he prefering only mice and not eating enough to get the weight he lost breeding back so he don't get to play) I think i had him take like 2 rat pups in the year or so he been with me.

I am currently planning on setting up a larger tub to put my butter and pinstripe clutchs in ( in the incubator) as it will be easier to tell the morphs from normals. specially if i use more than a single female with each male.

No matter how many times they breed, it's still a 50% chance per egg that it's going to be a morph when you are dealing with Co-Dom's.
As long as the male gets the proper rest between breeding sessions, the number of females he breeds doesn't matter. I personally would only go up to 5 females. Between 2 or 3 days on, then 2 or 3 off, any more females than that would limit the chances of lock-up per female. I'm not sure if I'm explaining my point clearly???...More females to go through, less frequency with each one.

I've been told by numerous people that cocktailing snakes produces more normals(by odds) than a single male X female breeding, but I'd be curious to the facts myself...

[mechnut450]

yeah after thinknig about it some more I may only do single or possible 2 females for the pairs. Simply cause I don't want a dozen or so normals to take care of. not that I have enough room to house another 12+ snakes with what I currently got.

Hi,

I've been told by numerous people that cocktailing snakes produces more normals(by odds) than a single male X female breeding, but I'd be curious to the facts myself...

I sat and worked this out once because, I too, kept hearing it.

Mathematically it has no basis in fact - there are exactly the same number of normal genes in the equation if you use heterozygous co-doms for example.

If an egg were capable of having more than two parents then it might be a factor but they can't.

What it does do statistically is divide the groups containing the genes from the side with multiple animals into the various possible but mutually exclusive outcomes.

So if you bred a male mojave and pastel to a normal female then each egg still has a 50% chance of being a normal statistically but the odds of it being a mojave are 25% and the chance of it being a pastel are 25%. All things being equal and assuming each male has a 50% chance of being the father.

So the odds of getting a morph or a normal remain unchanged from breeding using only one co-dom male.

In practice I doubt all males have the same chance owing to breeding timing before ovulation, sperm quality or a myriad of other factors. But there is no logical reason any of this would produce more chance of hatching a normal instead of a morph.
