ORIGINAL: peterK50 All thoroughbreeds are live cover, there is no artificial insemination. With the gestation period of a mare being 11 mos 15 days there is effectively one foal a year from that mare. So in 10 years she has 10 foals, & provides 50% of the genetic make-up, hardly a pollution of the breed with a genetic trait. The Cornell University Vet School did a study of breeding practices & found it in no way saturated by certain studs. There are always popular studs, Mr. Greeley was big, Strom Cat was big, now we're into A.P. Indy, Empire Maker,Fusaichi Pegasus, & Giants Causeway. Plenty of good studs in you have the cash. I believe Giants Causeway is standing for $170,000. You're misunderstanding. Number of individuals today doesn't matter. What matters is the number of alleles and their distribution in the breeds gene pool. With so few founders, around 100 tops, there was a very limited amount of variation in the breed when it was founded and after 250 odd years of breeding for specific characters the modern thoroughbred comes from a very homogenous gene pool. Effectively every stallion and mare are at most second cousins genetically and the longer the gene pool remains closed and the top studs do most of the breeding the situation will only grow worse.
