The years have passed since 2006, and during that time we have continued learning and, above all, understanding that in genetics one may know Mendel’s three laws (Gregor Mendel, 1822–1884)—the Law of Uniformity, the Law of Segregation, and the Law of Independent Assortment—but the reality is that genes are rather like dice in a cup, playing a game of Generala and trying to roll a perfect Generala on the first throw. The problem is that genes are not just five dice. There are more than 22 pairs contributed by each parent, combining randomly, with only the limited predictability provided by recessive and dominant traits. This often leaves us “guessing,” for certain characteristics, what percentage of offspring can be expected to express a particular trait. If we add to this the fact that the Arabian breed is evaluated according to five main characteristics, it becomes easy to understand that when we select a stallion with the aim of improving one or two particular traits, there is no genetic guarantee that the other three will remain unaffected. IS WHAT MAKES BREEDING SO FASCINATING. You never really know what will be born, and the result is always, and sometimes frustratingly, different from what you expected. There is an important warning I like to share with those who show horses: when a breeder produces a Grand Champion, he should not automatically assume that he has produced a HERD SIRE and use him as such. A Grand Champion is a Grand Champion on that particular day, against those particular stallions, and under that particular judge or panel of judges. On another day, competing against different horses and judged by different people, he would most likely receive a different evaluation. This leads us to conclude that choosing a stallion to become what we consider a true herd sire must be a highly analytical decision, based on an evaluation of that stallion’s performance throughout his breeding career. The fact that a stallion produces champions in other parts of the world and from different genetic backgrounds does not necessarily mean that he will produce the same results when crossed with our own maternal bloodlines. In my view, no matter how renowned a stallion may be, only about 1% or 2% of his offspring will represent a truly significant improvement. The greater the fame of a stallion—and the greater the number of winning offspring associated with his name—the more important it is to recognize that this may also simply reflect the fact that he has covered a very large number of mares each year. One must therefore look at the number of outstanding offspring in relation to the total number of breedings. Statistically, this tends to support my view that only around 1% to 2% of a stallion’s offspring will be truly exceptional.
