| Abstract: | Summary A breeding experiment was performed to examine the hypothesis that zebra finches (Taeniopygia guttata) preferentially mate with full sibs. Each bird had the opportunity to mate with one of 2 sibs or 28 nonsibs. Preferential mating between relatives did not occur. Offspring of sib pairs developed more slowly and sib pairs experienced more reproductive loss through death of offspring.Offprint requests to: N. Tyler Burley |
