Champion racehorses are thoroughly inbred
All thoroughbred horses alive today are descended from 28 animals imported from the Near East during the 17th and 18th centuries.
Advances in genetics have allowed researchers to trace the ancestry of the world’s 500,000 thoroughbreds to three stallions and 25 mares.
Close to 95 per cent of all purely bred male horses can be traced back to a horse called Darley Arabian, born just over 300 years ago.
Researchers at the BA Festival of Science in Dublin yesterday described how new techniques for reading the genetic profiles of racehorses will increasingly allow trainers to screen out inherited diseases and ultimately to work out why some perform better.
Patrick Cunningham, professor of animal genetics at Trinity College, Dublin, said: "We have been breeding horses for centuries but the new genetics has something to say not just for mice and humans but for horses, too."New methods of reading DNA have allowed us to identify the common ancestors of today’s thoroughbreds.
"We are starting a new study to see how we can harness modern molecular methods to produce sounder, faster, better horses."
Prof Cunningham examined the genetic profiles of thoroughbreds alive today and found they were descended from only 28 horses. Ten of these accounted for 80 per cent of those alive today.
A horse that lived in the late 17th century called Tregonwell’s Natural Barb Mare was identified as an ancestor of 14 per cent of living female thoroughbreds.
Thoroughbreds cannot by definition be the offspring of non-thoroughbred horses, so the population is becoming progressively more in-bred.
Prof Cunningham said the proportion of genes shared by any two thoroughbreds had risen from 31 per cent two centuries ago to around 47 per cent now.
Work on the human gene map has identified 140 genes related to performance and fitness, although more are likely to be discovered.
Despite the physiological differences, these discoveries can be adapted for horses to examine areas of performance such as how muscle cells respond to the pressure at the end of a race.
Dr Emmeline Hill, of University College Dublin, said that with owners spending as much as £7 million on thoroughbreds, genetic information would be used to try to breed winners.

Lets not go in to that this was a thread about sea the stars progeny not about anything else.
They do but i don’t think they have a feature where you can put a comment as why you want to follow that horse for.
ATR have released a new service Tracker its basically nag-me but you can add up to 50 horses for free and you can comment why you want to get nagged about them.
This is brilliant i don’t think there’s a mobile feature yet tho.
Another great FREE service from ATR
Looking at the next sale Tattersalls December Foals Sale 2011
There is one horse that stands out
984
B, C, f, Sea The Stars — Sadima (Sadler´s Wells)
Half brother to
Its going to make a fortune if it turns upIt Did go… But did not sell for the asking price. maybe yearling sales next year
I’m pretty Shaw that’s why they brought
New Approach – Authorized
for the bloodline. Even tho Sheikh Mohammed did it through his wife lol
they have brought a lot of
Teofilo
as-well
Galileo has proved his progeny can carry the bloodline class with
Teofilo
a group 1 winner in his first crop.
So you would praise a stallion who got a TRIUMPH HURDLE winner then? its good to know that a stallion can get top class NH winners because not all colts get to keep there Nuts do they?
they are both very good stallions at the end of the day
