This thread has been a good read so far.
But this post and the assumptions made in it I respectfully disagree with....
Years ago I went to see a man about something I do not remember about what. What I do remember is that he had a dog in his back yard that looked like one bad to the bone pitbull with a lab type head...I asked him what breed and he said half lab and half English bulldog...he also said she raised ten pups and all looked mostly like lab types except this one...
This was puzzling to me at first, and my final theory that made since me was this...The English bulldog gene pool deviates so much away from normal that it can not reproduce itself consistently when bred outside the English bulldog breed. We all know that the dog can barely breathe and needs air conditioning to survive the summer heat and most always the females deliver by C-section...it seems to me that quite a bit of the English bulldog exaggerated traits must be recessives...
It seems to me that some of that theory applies to the once in a lifetime dog because the deviate so much from the norm...we can use one of the greatest racehorses of all time as an example...Secretariet never reproduced himself...
The English bulldog and it’s genetic mutations are extremely proponent when bred on.
Esp when and if line crossed back to the original EB mix...
I could cite examples or many, many breeds that have been developed or transformed by EB blood being added. Some breeds fight the EB gene malfunctions line bred upon 10, 20 30 genes down the road after the cross. The casual observance of one F-1 litter (lab xEb) is no way to judge the genetic proponence of the two breeds crossed.
Esp, when words like ‘mostly’ are used in describing actual phenotypical variance. And , I’m such a casual way...
Did the litter on average have smaller teeth?
We’re they undershot, wry or even bit?
Shape of head? Was it rounder?
Eye shape?
Length of back? Was it shorter? Was it roached?
Breadth of chest?
Temperament?
Hips?
The EB is extremely proponent precisely because of a lot of things touched on in this thread...
It was tightly inbred for many generations for the abnormalities the breed possess.
Therefore it is proponent to throw Those same abnormalities when crossed on.
Semmes glad to see you are posting...you bring up some good questions and information...I do not have any proof of any kind on what I saw just an observation...actually there was no way to get close to that dog in that short period I was there on account he was very aggressive...my observation was that and me being a shade tree theorist by nature I had to reason out what I observed...
my questions theories went like this...if the other nine pups looked like a lab and only one looked somewhat like a bull dog then how could that be?
the genetics for the bulldog to be so under short...can hardly breath...can't take the heat and needs assistance to have a litter (C-section) then why is it that none of the pups favor the bulldog except one which really looked like a pitbull? My answer to this is because...I" finish later on account I have to leave for a while...
so why did the pups not favor the English bulldog phenotypically? Like I already mentioned before...the majority of the genes/traits that make up an English bulldog phenotypically have to be recessive...so when bred to the lab the dominant traits of the lab are displayed simply because they are dominant...recessive traits have to pair up one from the sire and one from the dam...if two recessives fair up for the color yellow then the pup will be yellow...if a black pairs up with yellow the pup will be yellow and so on...I am quick to develop a theory based on my past experience and what I see before my eyes...but I am quick to revise or change directions once I have been corrected and that does happen from time to time...
Semmes...if you don't mind explain and correct where I am wrong and explain the prepotency...as you can see I have my opinion and based on what you said I could be way off base...thanks
in my mind the bulldog is a breed that is desirable for fixing certain traits in other breeds...is it prepotency...my thoughts are no...instead the opposite is true...yes I am sure that they do carry many dominant traits...but I do know that know one in there right mind would like to breed undershot dogs that cant take the heat and worse yet not able to have pups without a C-section...
Semmes...
many years ago the racing greyhound became too timid to even race...a geneticist was hired to see what could be done to fix the problem...after some research he discovered that the English bulldog was the answer to the timid issue...as a youngster that sure didn't sound right to me at the time I was reading the article...the geneticist said that by the 4th generation the dogs should be almost pure greyhounds...he was wrong in that the f1 cross was almost pure greyhound phenotypically and the dogs were inheriting the fearless traits...
