Hybrid Vigour - info and examples!


Recommended Posts

now question ,,,on an other note ,,,as above

 

if 75lb greyhound x 32lb whippet ,,,,produced a 40lb whip/grey and turn out better than both parents surley is a hybrid then if not ?? then in the making,,and went on to breed to similar breedings,,off whip/greys,,,best to best,,,,,surely they are hybrids,,,,breed,,,best to best over the decades,,same breed

 

but ,,,then where does best lurcher to best lurcher stand??? me i would say there hybrids in there own right,,,,if proven :thumbs:

I see what you,re getting at mate but I think the Vigour would be lost when there was more x,s in the mix, the vigour would be more noticable in the 1st x and then less and less the more you x,d the progeny, imo :thumbs:

That's almost certainly about the interaction of genes that determine growth.   If I remember correctly a Liger is a male Lion and female Tiger cross and the genes that restrict growth exist either

It's just semantics, a hybrid is technically a cross between two species but as it's humans that define what a species is the term hybrid is open to interpretation.

 

For the sake of keeping the term meaningful it shouldn't be applied when you're talking about mating two genetically similar dogs even of they are both 'hybrids' (what most would call crosses)...Mating a brother and sister Whippet x Grey would mean they would be homozygous for alot of their genes which would defeat the object if the object was to add 'hybrid vigour'.

greyhoud 75lb ,,,and 32lb whippet,,,,,breed toghter---- produce a 20lb whip /grey,,,,,would that be a hybrid ????

 

Back in the late 60's,early 70's when Whippet/Greyhound 1st X's were becoming popular in the North East racing scene, the 1st X's were allways faster than the 2nd X's, (whippet/grey x whippet/grey), this was put down to "hybrid vigour" in the 1st X, which ws lost in the 2nd X's.

 

Cheers.

thays preety much my understanding of it pal the vigour only comes with the first x,, !!
