line breeding, inbreeding, selective breeding

Of course it's cause for concern, it's just that isn't real room for deformities other then neurological ones in an animal who has no limbs and can only breathe, eat, and poop. Also considering a snakes brain is simple as far as brains go (it only wants to breathe, eat, poop, and have sex) that there isn't much to go wrong; doesn't mean that something can't go wrong though.

I'm incredibly curious as to what the spider gene will look like after 4-5 pairings with each offspring mated off to another normal that is not related to each other in any way; not another morph (especially another recessive morph) just to make sure with a greater certainty that something like a spiders infamous neurological disorders can't be breed out.

Of course, scientifically, it'd technically take a whole lot of time and pairings to do so, but eh.

Scenerio ------->

Male ------- Female (Pair Alpha)
-----offspring------

Same Male (Alpha) ----- Different Female (Pair Bravo)
--------- offspring------------

Same Male (Alpha) ----- Different Female (Pair Charlie)
---------- offspring-----------

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
What would you call it if you bred the offspring of:

Alpha with Bravo -------> offspring (Delta)
Bravo with Charlie ------> offspring (Echo)
Alpha with Charlie ------> offspring (Foxtrot)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Lets take it another step....

breed:

Delta to Echo
Echo to Foxtrot
Delta to Foxtrot
and so on ...................

Oh boy. This is going to take a little thought.

Ok, if I follow correctly, you have one male {Alpha}, and three females{ Alpha, Bravo and Charlie} ?

You want to know what it's called if you breed the offspring of the double Alpha pair, with offspring from the Bravo pair, right ? That is a mild form of line breeding. These two sets of offspring still have a common ancestor in the Alpha male. It's the same with the other pairs, having one ancestor in common is a mild form of line breeding.

Now, by the time you breed the offspring of those offspring, you've taken the common ancestor down to great grandparent status, and at that point it is very mild line breeding at best.

I'm going to try and write this out a different way and see if I'm correct.

Pair 1: Spider male & pastel female - 1/4 chance at a bumblebee

Pair 2: Spider male & pinstripe female - 1/4 chance at a spinner

Pair 3: Spider male & Cinnamon female - 1/4 chance at a cinnabee

You breed the bumblebee to the spinner and you get a 2/16 spinner blast.

You breed the spinner to the cinnabee and you get a 2/16 chance at a cinna-spin

You breed the bumblebee to the cinnabee and you get a 2/16 chance at a pewter spider.

Now, breed these once again.

A spinner blast to a cinna-spin gives you a 2/64 chance at a pewter super spinner

A cinna-spin to a pewter spider gives you a 2/64 chance at a super cinny spinner blast

A pewter spider to a spinner blast gives you a 2/64 chance at a sterling pastel spinner.

So can you see the further out you take the common ancestor, the less like line breeding it is ? The genes are still there, but they hold less sway over the offspring.

Thanks for your breakdown it really put it into a better perspective :)
