[QUOTE="Anonymous, post: 1406969"] Here is more bull my statement full of it simply if you have sire name an dam from a breed you can tell by dna that is of that sire or dam but thats bull you take a cow that look like herford an say it is angus for all i care more bullRACT: Deoxyribonucleic acid-based tests were used to assign paternity to 625 calves from a multiplesire breeding pasture. There was a large variability in calf output and a large proportion of young bulls that did not sire any offspring. Five of 27 herd sires produced over 50% of the calves, whereas 10 sires produced no progeny and 9 of these were yearling bulls. A comparison was made between the paternity results obtained when using a DNA marker panel with a high (0.999), cumulative parentage exclusion probability (PE) and those obtained when using a marker panel with a lower PE (0.956).
