dog genetics

[riohog 5,621]

complicated ..job and im still not really sure about all this ...

 

is it 50/50 in a mating ..is the sire predominant geneticly ? or is it the bitch ?

 

 

what is the sire responsable for in the breeding ? speed .hight ,coulor or which part does the bitch play in all this ..as not all litters are uniform in size shape /or temperement

 

 

or is line /close breeding the only way to get these answersto garantee size ,shape speed temperement ,coulor ect .............

Ahhhhh the beauty of mother nature ...But i think its pretty much random on what dog gets what from its parents. I don't know about line/tight breeding for type but i think a lot of the congenital defects in pedigree/KC registered have come from tight/line breeding to fix certain traits in the breed ..this is only my thoughts and opinion before anyone jumps on my post and tells me i know nothing about breeding ..which i don't

ok line breeding can work and does to a degree but eventually some fault rears its head !

 

at what stage does outcrossing cure the fault /or eliminate it ?by introducing another dog ,into the breeding //or another bitch or is it some faults are acceptable /

the bitch is the main stay in any breeding,without a good bitch there will be no good pups.

 

ive bred mutations in birds for a number of years,differant colours from the norm,did this becouse i was intrested in genetics and it helps when applied to breeding dogs.not saying im the best in the world becouse im thick as fcuk lol but when your really intrested in something you learn no matter how hard it is.thats why i enjoy line breeding and inter breeding becouse i no what im getting each and every time,i wouldnt of known fcuk all if it wasnt for ken gould,as he was the one who got me into the mutations many years ago.the man is a mountain of knowledge and a straight talking no bullshit sort of guy as people no.

ok criss , you say the bitch is the mainstay of breeding .. but what i want to know pal ..is why ..

 

is that? and if that is the case ,why are stud dogs /horses ect so highly prized ?

[chris hickling 14]

becuse people dont want to be puting there stuff to shit.and lets face it pall we both no what your getting at.at the end of the day ive got a good reputation for what i breed and i dont like being lied to and putting my dogs to shit.ive stuck with the same breeds for years and and dont go in phases,i stick by what i no got no need to bullshit people like sum.

Right I'm not an expert, but I can tell you a few things. Put very simply, genes come in pairs,each pair are responsible for something or other, coat, colour, ear , or tail carriage and so on. Every dog or bitch has these pairs. The 2 genes in the pairs can be the same or they can be different. Perhaps the easiest pairs to demonstrate how they work is the sex gene,there are 2 types of sex gene , obviously male and female, the male gene being dominant, it over powers the female gene. So it works like this, each parent can only pass one gene from any given pair, these being passed at random. The female only has 2 female genes otherwise she would be male, so she passes a female gene to all her pups. The male has a female gene passed from it's mother and a male gene that over powers it, so he can pass either male or female gene at random. If he passes male the pup is male, if female the pup is female. This works with coat , colour, ear/tail carriage, the lot. It's all random, so dog or bitch are not responsible for specific characteristics due to their sex. Now the tricky bit is to learn which genes are dominant to the others. The only thing that to some extent is down to the bitch is temperament as some aspects of it are leaned and some genetic.

no no cris its a genuine thread with no specifics in mind ,, i will give you an example ... i know of 2 highly respected breeders of salukis .. there was a mating ,, of dogs between them ,,both very fast dogs and goog temperement .. the pups were born ..the owner of the bitch ..ket 2 pups a male and a female .. they ar now 15 months or so .. both very fast the male pup is the fastest ,, but you can hardly get close to these 2 they are extreamly nervious the dog pup being the worst ..the rest of the litter is ok no nerviouse ness and probebly not so qiick .. were did this nervious trate come from /// the dog /or the bitch nothing to do with upbringing as the man has kept dogs for 30/40 years so no illtratment ita a fault but wich side past it on?

I would say if it is only the 2 kept by one person out of the litter that are nervous then it definitely down to upbringing and not breeding/genetics as if it was genetic most of the pups would probably show an inherited trait to nervousness and not just the 2 kept by one person, JMHO

I agree, it's most likely down to socialisation.

i dont believe that .. ok the nerviousness is really apparent with strangers ,both pups are well socialised and live comfortably and interact fine with other dogs ,, so i believe it is something genetic forgot to say... the nerveiousness is more pronounced with men rather than women !

[riohog 5,621]

would you take a risk and use this as a stud dog ? with the chance of this trait being passed on ,

 

or are you 100%sure its NOT genetic

All the facts you've stated, suggest a lack of socialization.

Some pups are just born nervous and aint shit you can do about it.

 

The only reason that some folks might say that a bitch is always more important is because of mitochondrial DNA. They get none of that from their daddy cause it maternally inherited for the most part. There are only at the most like 1000 molecules of mtDNA in sperm but something like a 1,000,000 in an egg and also I believe that the "fetus" or whatever you call it in a dog (HAHA) absorbs some mtDNA also through the amniotic fluid. Nuclear DNA is the 50/50 deal and there is no disputing that. There ya go, thats it. But DNA is crazy and it can be pieced together so many different ways and if it dont fit right then it just dont.

yeah hear what you are saying dan .. it is a science but not an exact science unless it is replecated through 1005 cloning dolly the sheep job
