ABSTRACT Behavioral studies of white-tailed deer (Odocoileus virginianus) often assign mother-offspring relationships based on common capture of juveniles with adult deer, assuming that fawns associate closely with mothers. We tested this assumption using genetic parentage to assess mother-offspring relationships within capture groups based on data from 10 polymorphic microsatellite loci. At the 80% confidence level, we assigned maternity to 43% and 51% of juveniles captured with an adult female in 2 respective study areas. Capture with their mother did not differ by sex of juveniles in either study area, and limiting our analysis to capture groups that most represent family groups (i.e., one ad F with 1–3 juv) did not increase maternity assignment (35%). Our results indicate that common capture may be a poor indicator of mother-offspring relationships in many field settings. We recommend genetic verification of family relationships. 相似文献

Here we report development and characterization of seven polymorphic loci derived from grass rockfish (Sebastes rastrelliger) genomic DNA phagemid libraries enriched for microsatellite motifs. Within grass rockfish, average allelic diversity was 11.3 alleles per locus and average heterozygosity was 0.73. The seven loci also were surveyed in 10 related species of Sebastes, where allelic diversity ranged from highly polymorphic to monomorphic. Deviations from Hardy–Weinberg were nonsignificant in all but one species/locus combination suggesting low occurrence of null alleles. Significant linkage disequilibrium was detected among three loci, but these events were limited to a single species in each case. 相似文献
