[QUOTE="HerefordSire, post: 380367, member: 4437"] I understand English pretty well, thank you! [b]I should have never used the word "blood" in the context. My mistake. By the way, that wasn't supposed to be an english lesson. Just me communicating to you my meaning.[/b] I am also well aware of terms used when parentage are discussed. [b]?. I hope so as you are my teacher. :cboy: [/b] My point is, that if there was something else, but herefords in the 1966 "blood" as you prefer to call it, it wasn't recorded or disclosed and would have no influence in the calculations that came to the 11.5%. If any other "blood" was introduced after 1966, it would still have no influence on the calculations that rendered the 9.8 % in 1990 as they use pedigree records to do the calculations. If something isn't officially recorded it can't have any influence on the official % of inbreeding. [b]Good point! Now you have me thinking. If there was a dilution, the animal(s) would not be registered. If DNA tests were done on all Herefords alive, could it be proved if there was a non-Hereford in the gene pool?
