How important is the gyp?

HOW IMPORTANT IS THE GYP?


Through the years I have always believed that the genes a pup inherits are 50% from the mother and 50% from the father. From the article I just read it may lean a little more toward the mother giving more than the 50%. You decide.... ENJOY! LPD

Dr. Jim Gannon has penned the following to keep participants informed about important breeding issues. Let me ask the simple question — Do the sire and dam have equal input into the inherited qualities of the litter?

Now, of course, 99% of respondents will automatically say - Yes - but is that the reality? According to the information from Theresa Garton in Oklahoma City in USA, research has revealed irrefutable scientific evidence that challenges, and disproves, that popular traditional belief.

So the real ANSWER is - that the bitch actually contributes more than 50% genetically to her litter. For the scientifically minded, this is how the apparent heresy comes about: -Every structure within the body is composed of millions of tiny cells (brain cells, liver cells, kidney cells, skin cells, etc.) -Every cell has three important components - a nucleus containing the genes hidden in the coils of DNA - a membrane (like a skin) that holds the contents of the cell together-and, the cytoplasm which is a jelly-like fluid filling the cell and supporting some other structures essential to cell operation, and, to life itself.

Two of these life-support structures, within the cytoplasm, are the Mitochondria, and the Golgi apparatus.

Now, the egg produced in the ovary is similar to any of the other millions of cells of which the body is composed except it has only 50% of the mother's genetic material (DNA) in its nucleus, same as the sire has in his sperm, BUT the egg also contains the mother's cytoplasmic life-support Mitochondria, Golgi Apparatus, and all of the other enzymes within the normal cytoplasm.

On the other hand, the sperm contributed by the sire contains only the usual 50% of his genetic DNA in its nucleus, plus a tail to enable directional guidance when swimming, and a short-lived energy supply for the swim-but virtually no cytoplasm. (And consequently, none of its important life-supporting Mitochondria or Golgi apparatus structures - these come only from the bitch.

Fertilization occurs when the sperm of the sire locates and enters the egg of the bitch, and the newly formed cell develops into a pup over the next nine weeks. However, it becomes immediately apparent that the pup which [SIZE=3][COLOR=#333333]develops from that fertilized egg will have equal DNA contributions (genes) from each parent (50% DNA from each) within its nucleus, BUT, will also have all of the essential life-support systems of the Mitochondria and Golgi Apparatus from its mother's egg within its cytoplasm [/COLOR][/SIZE][FONT=Times New Roman][SIZE=3][FONT=Comic Sans MS]— and these are inherited ONLY from the mother.

[B][SIZE=3][FONT=Comic Sans MS][COLOR=#333333]Without these life-support structures, the [/COLOR][COLOR=#333333]genes within the newly formed nucleus [/COLOR][COLOR=#333333]would never survive to reach their [/COLOR][COLOR=#333333]genetic potential [/COLOR][COLOR=#333333]—and, the efficiency of [/COLOR][COLOR=#333333]the working cell in later life will be [/COLOR][COLOR=#333333]totally dependent upon these [/COLOR][COLOR=#333333]cytoplasmic structures inherited from the [/COLOR][/FONT][/SIZE][COLOR=#333333][SIZE=3][FONT=Comic Sans MS]bitch.

A lot of scientific jargon there. But definitely agree with last part.

 

That would all be very important if I believed that there was a game gene which surprisingly a lot of people believe that there is

 

I want to here more talk about the game gene.

 

couldn't agree more. a good stud is nice, but a good bitch is priceless.

 

what i wouldn't do to have this one back , http://www.apbt.online-pedigrees.com/modules.php?name=Public&file=printPedigree&dog_id=308423,,

 

i enjoyed this post immensely. i know both parents are important but i've always believed the female mattered more. it's also another reason i feed raw during the pregnancy.

 

Good theories...

 

I didn't see that one coming!

 

I was told a good male is great for making money(stud fees), a great brood bitch is what builds a yard. I am sure this is not always the case but maybe more times than not?

 

Been more than a year that Dr Lector has been on this site. Wish he was still posting as I enjoy reading these posts.

 

You would think more kennels would promote more females, with that being said you are correct on the main emphasis being males.

 

I have used the method of always breeding for a better female since day 1.
Even though you may breed heavy on a male, you still go back to the best females both bred & performance to enhance the family.
Of course I like to use examples to better explain my point.
Been line breeding to get this female just to go back to her Uncles . ONLINE PEDIGREES :: [470679] :: HICKS WOODLINE BITCH , Even though Line bred Crossfire, a male , who's line bred on Johnie Rockhead another male, breeding is based on getting a better female to go with a litter full of good males in her mothers litter. Should get the results looking for in this breeding http://www.apbt.online-pedigrees.com/modules.php?name=Public&file=printPedigree&dog_id=470681.
Can't speak for anyone else, but I always breed for a better female.

 

stay in controle of your bitches ..is that not saying enough lol

 

Interesting article, but the Golgi apparatus and mitochondria don't pass traits to the offspring.

 

I seem to feel that some pups favor the bitch and some more favor the sire ,just from looking at any litter you will see this why I have no idea you would think they would all look alike since aall the ingredients are the same yet they do not as tiny dna differences occur look at any little some have more of either I have always felt eyes don't lie ...But it has always been important to take care of the Bitch as she is gold with the highest quality food and care you can afford..

 

The scientific side of breeding is interesting to read about however Earl Tudor didn't know a single thing about the "science" of breeding yet he is still considered to be one of the best breeders ever. Come to think of it Most of the best breeders ever don't know how to spell the word Mitochondria let alone what it is.

 

Good insight and post TDK, I couldnt agree more and think there should be a moral ban on the incubator theory...

 

I fully agree with TDK on that post, very good insight and i will say this, not that it's a fact maybe it's just circumstance but over the years many of the quote on quote Best breeders that are known to public and even the great private breeders that I personally know of. All had a very strict line when it came to females, many were harder on females even if they were not getting shown. Many had a no nonsense mentality and wanted to see the dominant qualities from their gyps.
