Inbreeding depression and selective breeding?

[Krynn]

With the constant plethora of threads relating to genetic abnormalities (spider wobble, kinking etc.) i am constantly thinking about the genetic quality of the ball python population in general. I am posting this thread to see what general consensus is in the BP community on a few genetics topics.

Inbreeding depression:

Ill start off with the wikkipedia definition:
Inbreeding depression is the reduced fitness in a given population as a result of breeding of related individuals. It is often the result of a population bottleneck. In general, the higher the genetic variation within a breeding population, the less likely it is to suffer from inbreeding depression.

Inbreeding seems to be a fairly common practice in ball python breeding. After all, inbreeding is often the only way to isolate a new gene that pops up due to genetic mutation. Although inbreeding can be a very useful technique to isolate genes, it seems to me that it is done quite a bit more then necessary for the ball python population in general. For example, "breeding pairs" are often sold from the same clutch, and that clutch may have already been subject to inbreeding in its recent ancestors. Is inbreeding depression something that you guys strongly consider when you are purchasing and pairing up BPs during the breeding season? Do you guys think that certain genetic problems (in particular kinking) may be linked to inbreeding depression in certain lines?

Selective Breeding:

In my opinion, the lack of selective breeding is having a fairly strong negative impact on the genetic quality of BPs. Although selective breeding can have an impact on alot of visual aspects of color mutations for example (perhaps the browning out of pastel BPs) I am going to focus on a trait that effect the overall health of a BP.

Since the head wobble seems to be tightly associated with the spider morph, it seems to be less likely that it is the result of inbreeding depression. I think that the head wobble is a prime example of why a lack of artificial selection can degrade the genetic quality of a species. This hypothesis is based off of a certain assumption that i hope to get a bit more insight from in this post:

It is my assumption that people will continue to breed an individual with the spider head wobble. So my questions to you guys are:
1.) Do you selectively breed your ball pythons, or do you breed anything that WILL breed?
2.) Do you think that consistently breeding BPS with "faulty" genes is polluting the BP gene pool?

I realize that this post may be a bit controversial for many, but I think that the responses to this post will be quite interesting in viewing what the general consensus in on these topics. Let me know what you guys think!
