本文提出了一种划分选择群体遗传趋势的方法。遗传增益的每一部分都是不同动物群体的孟德尔抽样项，有时可以分配给不同的选择政策。该方法是基于一个简单的转换的预测育种值。用两个模拟实例说明了该过程。在第一个例子中，遗传趋势被分成两部分，一部分来自于对公畜的选择，另一部分来自于对母畜的选择。第二个例子说明了如何评估人工授精中心对整个群体遗传增益的影响。
In this note, a procedure to partition the genetic trend of a selected population is presented. Each part of the genetic gain accounts for the Mendelian sampling terms of different groups of animals, which can be sometimes assigned to different selection policies. The method is based on a simple transformation of the predicted breeding values. The procedure was illustrated with two simulated examples. In the first example, the genetic trend is partitioned into two pieces, one coming from the selection on sires and the other coming from the selection on dams. The second example shows how the impact of an artificial insemination center in the genetic gain of the whole population can be evaluated.
