to be a true hybrid, would the offspring be sterile???

 

 

like mules

think yiur right to prevent further generations from the offspring

like mules

mules as in birds goldfinchx any other finch are classed as hybrids they are both finches . so why can a canine x canine from different countrys not be classed as a hybrid

aint a mule a canary x finch???

 

i was actually refering to a horse/donkey,= mule, like the hillbilly dan edwards uses

 

i will be 1st to admit on this thread that i am a bit baffled by it all, i didnae think 2 dogs x'd could give hybrid vigour...

but there again there is a lot cleverer folk than me on here, so ill stand corrected

well you tell us all , and prove that it is a hybrid you can call it what the f. you like doesent meen its correct /

finch x canary is classed as a mule..... finch x finch is a hybrid and the result in both is classed as is hybrid vigour

well them beddi x,s must be hybrids according to some experts on here they can pull red stags must be right then!!!

Sooo much confusion lol.

 

Hybrid vigour (heterosis) is the term used to define the crossing of species but species are only what science terms as a specific type, if our dogs (say a Terrier and a Whippet) were wild then science would almost certainly class them as separate species because they are so genetically dissimilar...Even very closely related dogs (say Greyhounds and Whippets) would be classed as sub-species or regional variants.

 

Crosses between species are very rarely infertile, it's mostly to do with the mode of inheritance of the fertility genes. Since the mode of inheritance is similar in most species a surprising amount of hybrids are viable both in terms of their existence and their fertility.

 

So yes, you can effectively have hybrid vigour within a species. The idea is that most of the rare 'bad' genes are recessive and you need two copies of those genes for them to be expressed. This means that both parents have to carry the gene (homozygous) for it to affect the pups...This is mathematically much less likely if the parents are genetically dissimilar (heterozygous). Hybrids (or crosses between breeds/types) therefore have a much lower chance (in the absence of genetic testing and selective breeding) of being affected by rare genetic disorders.

 

Another major benefit is the watering down of exaggeration.

 

The disadvantage is unpredictable results. You get 'less even' litters showing a larger degree of variation.

Yeah what he says

[bird 9,943]

The mixing of breeds that have positives that can help balance the negatives is a good way of creating a stronger dog. If you were to breed dogs that have common problems like bad hips then you would be missing out on the possitive aspect of breeding different breeds together. Of course if you use healthy dogs both with possitive aspects like bull x grey then you should get a dog that is healtier than breeding to a dog that carries the same negative traits.

 

true, breeds that get alot of HD. GSD ,Bullmastiffs, even Pits + staffs get it quite bad. If bred to a greyhound either 4 breeds, would have better Hips , i never heard of any greyhounds getting it, i worked at racing kennels few years ago. The get other probs (feet+wrist) but all had good Hips. So it as as got to be hybrid vigor by useing genes that dont carry it from 1 parent.I dont think bullxgreys get it either, well ive never heard of any or what ive kept suffer from it

what about the ligers (lion x tiger) they are both feline but the offspring cant breed(i think)but they grow much bigger than either parent and that is classed as hybrid vigour
