Inbreeding depression, or the reduction in fitness due to mating between
close relatives, is a key issue in biology today. Inbreeding negatively
affects many fitness-related traits, including survival and reproductive
success. Despite this, very few studies have quantified the effects of
inbreeding on vertebrate gamete traits under controlled breeding
conditions using a full-sib mating approach. Here, we provide
comprehensive evidence for the negative effect of inbreeding on sperm
traits in a bird, the zebra finch Taeniopygia guttata. We compared sperm
characteristics of both inbred (pedigree F = 0.25) and outbred (pedigree F
= 0) individuals from two captive populations, one domesticated and one
recently wild-derived, raised under standardized conditions. As normal
spermatozoa morphology did not differ consistently between inbred and
outbred individuals, our study confirms the hypothesis that sperm
morphology is not particularly susceptible to inbreeding depression.
Inbreeding did, however, lead to significantly lower sperm motility and a
substantially higher percentage of abnormal spermatozoa in ejaculate.
These results were consistent across both study populations, confirming
the generality and reliability of our findings.
