Genetically predisposed aggression (AKA is aggression hereditary?)

Placed before you is the discussion on whether you think aggression is hereditary?

I'll start off with with my view that it IS. I have a female Okeetee that as an adolescent was a HUGE biter, her biting was in fact why she was given to me. As she grew into adulthood however she hardly ever bites anymore.

I have found though that all her offspring are very feisty! Way more so than any other clutch from any other female I have. I have breed her for 3 years now, and to 2 different males. The male from the first 2 clutches was also very aggressive and I originally attributed the babies disposition to the father. However the different male that fathered her clutch this year also fathered 2 other clutches of which range from ultra tame to what I consider pretty normal for a baby while the Okeetee's babies are still just as feisty as in years past.

Conclusion, she has a dominate gene that is seen in her offspring of which the phenotype is overly aggressive babies.

I have no idea about snake genetics however, I think that it could be hereditary. Why not? Some traits are hereditary in humans and other animals so why not snakes?

And that guy..... it having a BAD day!
 
I think it can be hereditary, too. I have no snake breeding experience but I have calm and feisty snakes (2 corns and 1 king). So far my eldest corn is the most calm snake I have ever met (even as a baby) and I would love to breed her to an equally calm male and see if the babies are just as calm.
 
I think at least some aspect of aggression is possibly hereditary. Though I don't think it is governed by simple dominant/recessive genetics.

The guy I got my GTP from has a very docile line of GTP's, and produces very docile GTP's from them. The first GTP I ever handled was one of his adults, and it was more docile/calm than most of my cornsnakes. I can only assume that they are many generations removed from the wild.
 
I would have to agree that it could likely be hereditary. I also have heard (& believe) that certain morphs can tend to be more aggressive as well.
Other factors being individual personality & age come into play as well.
 
I couldnt agree more, but have a pair of calm a pair of flighty and a pair of nasty little buggers ( het/morph pairs ) I intend to keep a journal on and monitor the behavior change as they grow into adulthood to how their babies are personality wise.. Should be interesting.. Very catchy topic!
 
I believe personality is much more genetic that we would like to think. Corn snakes are generally calm snakes, Honduran milk snakes are generally spastics. That is genetic. I has to be. A Doberman will bite you and Cocker Spaniel won't, that is genetic.

I agree up to the Dog thing, I work at a Vet Hosp. And have handled MANY animals, the surprisingly, the Dobes are more fearful, and the cockers are more likely to be bouncy and nippy. Also showing dogs in Confirmation and trialing agility and obedience, I must say, I have found many " Danger " breeds like Am. Staffs, GSD's, and Dobes to have the nicer personality, than the smaller more nippy breeds, but I've also met ALOT of very sound temp. cockers. I happen to love both Cockers and Dobies.
Good thought though.
PS. GENETICS DOES have a role in dog personality as well, ever heard of "springer range synd." ? that is a gentic bred thing, but accident of course, but happens when the springer breeders bred for look rather than temp, and they had lines of dogs coming out with these "check out" points where they almost turn their brain off when something doesnt run their way. Google Springer Rage Syndrome if you dont believe me =)
 
My most nervous adults tend to have more bitey babies per clutch. Anecdotal, yes, but I've seen it enough times to feel pretty darn certain.
