Genomic Inbreeding and Relatedness in Wild Panda Populations
Inbreeding and relatedness in wild panda populations are important parameters for panda conservation. Habitat loss and fragmentation are expected to increase inbreeding but the actual inbreeding levels in natural panda habitats were unknown. Using 150,025 SNPs and 14,926 SNPs selected from published whole-genome sequences, we estimated genomic inbreeding coefficients and relatedness of 49 panda...
متن کاملInbreeding effects in wild populations
USA. Small and isolated populations are inherently more vulnerable to external environmental perturbations and chance fluctuations in local survival and fecundity [termed ‘ENVIRONMENTAL STOCHASTICITY’ and ‘DEMOGRAPHIC STOCHASTICITY’, respectively (see Glossary)]. Are they also threatened by inbreeding and the loss of genetic diversity? With data on the effects of inbreeding in wild populations ...
متن کاملExact Inbreeding Coefficients in Populations
A theory is given that allows inbreeding coefficients to be calculated exactly for populations with overlapping generations. Emphasis is placed on providing equations well suited for computer iteration. Both monoecious and dioecious populations are considered and family size is not restricted to being Poisson. One-locus and two-locus inbreeding coefficients are evaluated, although the reader ma...
متن کاملPaternity and relatedness in wild chimpanzee communities.
The genetic structure of three contiguous wild chimpanzee communities in West Africa was examined to determine the extent to which the community, the mixed-sex social unit of chimpanzees, represents a closed reproductive unit. An analysis of paternity for 41 offspring resulted in 34 cases of paternity assignment to an adult male belonging to the same community. Among the 14 offspring for which ...
متن کاملThe Consequences of Polyandry for Sibship Structures, Distributions of Relationships and Relatedness, and Potential for Inbreeding in a Wild Population
The evolutionary benefits of simultaneous polyandry (female multiple mating within a single reproductive event) remain elusive. One potential benefit could arise if polyandry alters sibship structures and consequent relationships and relatedness among females’ descendants, thereby intrinsically reducing future inbreeding risk (the indirect inbreeding avoidance hypothesis). However such effects ...
