Pit Bull Chat Forum

Welcome to Pit Bull Chat!

We are a diverse group of Pit Bull enthusiasts devoted to the preservation of the American Pit Bull Terrier.

Our educational and informational discussion forum about the American Pit Bull Terrier and all other bull breeds is a venue for members to discuss topics, share ideas and come together with the common goal to preserve and promote our canine breed of choice.

Here you will find discussions on topics concerning health, training, events, rescue, breed specific legislation and history. We are the premier forum for America’s dog, The American Pit Bull Terrier.

We welcome you and invite you to join our family.

    We decided to spruce things up and fix some things under the hood. If you notice any issues, feel free to contact us as we're sure there are a few things here or there that we might have missed in our upgrade.

So, you THINK you might have a "Pit Bull"? Genotype vs Phenotype!

thats a very interesting concept and highly plausible. obviously the apbt is, like all other dogs, the product of selective breeding by humans. so therefore it must be possible- even if improbable that somewhere out there right now there are puppies being born that share the same dna mixes and qualities as apbt's even though neither parents wouldn't be classed as apbt's in their own right. the variation among the so called pure bred dogs of today supports your theory and I applaud it.

A simple example is a seed dropped on fertile dirt and a similiar seed dropped on rocky ground. Both may grow but because of environmental differences, the resulting plants might have different physical characteristics. That difference can actually "alter or change" the effect of genes on subsequent generations.

Very interesting post but I just want to point out that the above is not true. The difference in the appearance of the plant grown in lush fertile soil vs. one grown on rocky poor soil is the the phenotype. Each two plants have the exact same genotype and would be able to produce equally healthy offspring. The plant's phenotypes are different because of their environment, not their genes, so they have no genetic differences to pass on to the next generation.

What you are describing is actually a Lamarkian explanation for evolution that states that evolution occurs due to traits acquired during the organisms lifetime. It was discredited by newer findings like natural selection and genes.

Again, an interesting post but I just wanted to clear that up.

I clearly stated that it alters or changes the "effect" of genes in subsequent generations...ie. the phenotype. I did not say that it "actually" alters or changes the genes in subsequent generations...ie. the genotype as in evolution (or natural selection).

I put this statement first "***This is going to be a fairly simplistic model skewed toward "Pit Bulls" in general***" to keep things very simple. It was not meant to prove or disprove soft inheritence or evolution.

I added a statement at the bottom to inform readers that this thread is for fun!

I love this post, and I would buy a bumper sticker too, I want one but haven't really looked yet for a "stop the litter, spay and neuter" one I'm sure my vet probably has them because its what the sign says outside the office hehe...but really, I do think this post is great, it is very informative and I just wish we could as a forum try to crack down on BYB...maybe by not buying from them or something I don't know, just an idea.

that was really interesting.. think I will reread it a few times so that it all sinks in, as it was something I had not thought bout until reading it. Thanks;)

good read. so answer me this. the true apbt was small to medium maybe up to 60lbs. how do we have 100+ pounders that look stubby to tall and lanky that are registered????.... Sounds like a lot of phenotype to me!

I think passing laws to require breeders to have a background in genetics would be much better than BSL (I know-preaching to the choir here)!!!

A dog a owned years ago had a mutt litter prior to being spayed and I had an idiot actually tell me that if I bred her 3X to a purebred male then on her third litter the pups would all be pure-breds again, but I'd have to go through 2 more mixed litters because she had bred to something else! Spay/Neuter became real clear that day!

breed??

I expect it has been asked a trillion times..but what breed/type was "Daddy",could you perhaps tell me,I am very curious to know having seen AKC AMstaffs at European and American shows (GORGEOUS BTW) We are not by law allowed any of these breeds here in UK,a shame indeed,but it makes it even harder to educate yourself. And American Bully..where did they come from ?
