Abstract

A selection experiment, conducted for 17 generations, compared a selected population mated in a cyclic manner with alternating generations of inbreeding and outbreeding, a selected population mated at random and a randomly mated, randomly selected control population. Trends in the number of birds available for selection and number selected are presented for each population. Actual and theoretical levels of inbreeding for each population were similar. Samples of all populations were subjected to continuous full-sib inbreeding at generation 12. All populations were sensitive to inbreeding depression. However, the cyclic mated population had greater reproductive fitness after continued intensive breeding.

摘要

一个选择实验进行了 17 代，比较了一个通过循环交配方式进行交配的选择群体，该群体在交替的自交和杂交世代中进行交配，一个随机交配的选择群体和一个随机交配、随机选择的对照群体。每个群体的可供选择鸟类数量和选择数量的趋势都有所呈现。每个群体的实际和理论自交水平相似。所有群体的样本在第 12 代都进行了连续的全同胞近交。所有群体都对自交衰退敏感。然而，在持续的密集繁殖后，周期性交配的群体具有更高的繁殖适应性。
