"Breed assignment was performed on bull identified as Saltaire Platinum M2708 & ADCA 6504. Analyses were done based on genotypes for 20 unlinked microsatellite markers. Assignment of an individual to a breed is based on estimating the probability of the complete genotype in each of the reference breeds. No information of source breed was assumed for the bull. The 14 reference breeds are Angus, Ayrshire, British White, Charolais, Dexter, Friesian, Gelbvieh, Hereford, Jersey, Limousin, Maine Anjou, Shorthorn, Simmental and Texas Longhorn. Based on microsatellite markers, there was no detectable contribution from any of the other reference breeds. Breed analyses provide no evidence of a genetic background other than Dexter. Cecilia Penedo, PhD Director Associate Researcher-Geneticist" |

Yes I read the report BUT he could also be 89% ANGUS too.

Not trying to cause a issue just saying until the test can absolutely define breeds I will play it safe . My grandfather and fathers generations raised and lived through the Herford B S and now people want the type of Herford my Great grandfather had. Now they are outcrossing to get back to the original because they outcrossed to get were they are now. Please note Kirk I will not judge any bodies herd so do not judge mine !!

20 markers thats all they compare against seams like a low number. Secondly what animals was he compared against? Are we talking the current breeding population of dexters? if so then well duh he matched he is the patriarch of most of the US herd. He should have been compared against animals that do not have the documented upgrades.

They specifically looked for Angus (and many other breeds), and they found ZERO trace of Angus. The analysis was completed by the experts at UC Davis VGL |

He should have been compared against animals that do not have the documented upgrades. The PHD genetics experts at UC Davis selected the appropriate markers to use. Judy says UC Davis is the best of the best. They compared Saltaire Platinum with horned traditional dexters from the Legacy Database.... they EXCLUDED any with Saltaire Platinum anywhere on the pedigree Saltaire Platinum is tested pure dexter..... are any of yours tested pure dexter? Better get busy. |

Must be a republican influenced comment. Don't let science confuse your issues (like "Global warming" among other things!) |

I remember 11 years ago, seeing Judy post on old boards that she hoped that someday we would have a DNA test that could test an animal to see if it was purebred, or not. That day is here.
I'm sure traditionalists are thrilled to see that Saltaire Platinum is PURE dexter. Now, traditional breeders can simply select for the traditional traits they love, and stop worrying about whether Saltaire Platinum is on the pedigree or not.

Kirk and edude2 read the last paragraph carefully same H3Y1 is typical
in Dexter cattle BUT!!! not exclusive also found in other British breeds
such as ANGUS AND SHORTHORN . Take off your blinders. OH YA I am a PROUD
American and hold my own BELIEFS as I want or have we LOST that right.
It is also called CLIMATE CHANGE now!

Kirk and edude2 read the last paragraph carefully same H3Y1 is typical in Dexter cattle BUT!!! not exclusive also found in other British breeds such as ANGUS AND SHORTHORN . The last paragraph talks about a separate analysis that they perform on the Y-Chromosome (sex chromosome) of male animals. Since only males carry the Y Chromosome and females do not, then Males (including humans) get a clone of their father's Y Chromosome. So all male animals have a cloned copy of their father's father's father's father's father's father's father's father's father's father's father's father's Y Chromosome. Geneticists can trace these male lines far back in time based on occasional minor mutations made in the cloning process. Because many male lines get broken and go extinct, there are a limited few male lines in any species and they often go back 40,000 to 100,000 years or more. Geneticists type these male chromosomes for a breed and give them classification codes like H3Y1. The H3Y1 Haplotype/Haplogroup means that all the males with this type, all descend from a common male-line ancestor thousands of years ago (way before any modern breeds came about) The purest of pure Dexters come from several different male lines including haplogroup/haplotype H3Y1 If you trace Saltaire Platinum's father's, father's father's father's father's line back, you'll run into Grinstead Jackdaw. In Dexters, Grinstead Jackdaw and all the sons of sons of sons of sons of sons of Grinstead Jackdaw would be expected to be Haplotype H3Y1 and it could go back many thousands of years..... It certainly makes sense that lots of "Traditional" Dexters would be H3Y1, along with other British Isle breeds. Some of your own "Traditional" dexters may also be H3Y1 |

OH YA I am a PROUD American and hold my own BELIEFS as I want or have we LOST that right. It is also called CLIMATE CHANGE now! You pulled your point out of context. The sentence before, which is part of the whole report states "Saltaire Platinum maps to the Dexter breed with high likelihood. Based on microsatellite markers, there was no detectable contribution from any of the other reference breeds." Simply put for your understanding is that there are several markers but only one - H3Y1 is associated with angus and shorthorn as well as dexters. That is why AA Markers are dexter and this H3Y1 you are hanging your hopes and dreams on, when added to the mix gives Saltaire Platinum a .89. NONE of the other markers for angus and shorthorn are found in the test. Rather than giving your opinion based on one statement, you have to read the whole in context. Here is a link to the UC Davis site on genetic testing of cattle breeds:http://r.search.yahoo.com/_ylt=A0LEVidwJcZVSPEAmC8nnIlQ;_ylu=X3oDMTByOHZyb21tBGNvbG8DYmYxBHBvcwMxBHZ0aWQDBHNlYwNzcg--/RV=2/RE=1439077873/RO=10/RU=http%3a%2f%2fanimalscience.ucdavis.edu%2fanimalbiotech%2fOutreach%2fVanEenennaam%2520PopularPressArticle.pdf/RK=0/RS=71HHYG3Qgj3d4MYA_Jw1q_FsVIY- |

They have done it through intimidation, insult and false innuendo. They have even used character assassination. You certainly have the right to believe what you want, but you don't have the right to attack, insult or belittle others because of your lack of understanding of the scientific principles behind bovine genetics. In Arkansas, we have a saying that" It ain't what you don't know, that makes you ignorant. It's what you know, that ain't so". My hope is that now the testing is done, all fringe groups can rejoin the Dexter Breed and quit the in fighting and opt in, instead of the opposite , to support ALL dexter owners regardless of the TYPE they are breeding for. This is another reason the Association has moved to bull and heifer genotyping. We have finally evolved beyond guessing to being able to verify. Behaving like angry uneducated children, does nothing to promote this remarkable breed, only the egos of those hurling the vitriol. |

Some of your own "Traditional" dexters may also be H3Y1 Kirk, Your explanation here is an excellent simplification of facts, stated in layman's terms. It is a great answer. However, some closed minded individuals that have an agenda of their own will keep their minds closed without even attempting to understand. Please keep on discussing so that one day Dexter owners can work together and not be divisive and disparaging of each other. |
