Fifteen bovine microsatellites were evaluated for use in parentage testing in 725 bison from 14 public populations, 178 bison from two private ranches and 107 domestic cattle from five different breeds. The number of alleles per locus ranged from five to 16 in bison and from five to 13 in cattle. On average, expected heterozygosity, polymorphism information content (PIC) and probability of excl...

When a parent's parentage differs across breeding attempts, established theory predicts that the parent should invest more in a brood when perceived parentage is high. We present a model of parental investment in which offspring unrelated to the parent have a competitive advantage over the parent's own offspring and take a larger share of investment. We show that this can weaken or, if the comp...

Zoo-based captive breeding programs typically rely on accurate pedigrees to maintain long-term population genetic diversity and prevent close inbreeding. For many mixed-sex captive populations, it is difficult to assign parentage of offspring with certainty without conducting DNA-based parentage analyses. Using the demographic parameters of a North American captive population of Arabian oryx (O...

The formulae for computing the so-called Sib Index using codominant alleles for (1) full-sib and (2) half-sib parentage are given. Hypothesis testing is based on the distribution of conditional likelihood ratio or Bayes' factor. Thresholds for rejecting the null hypothesis and P-values were obtained in function of the number of alleles and their frequency distributions. Simulations showed that ...

Chinese jujube (Ziziphus jujuba Mill.) is an economically important fruit tree with outstanding adaptability to marginal lands and a broad range of climate conditions. There are over 800 cultivars, mostly landraces from China. However, high rate mislabeling in germplasm restricts the sharing information materials among researchers hampers use breeding. In present study, we developed large panel...

the present study was to construct a parentage verification system for iranian caspian horse. a total number of 45 caspian horse samples including 14 foals for parentage verification, 17 stallion and 14 mare for individual identification were genotyped. genomic dna was extracted from whole blood and the genotype were analysed by pcr procedure and using 7 microsatellite markers (aht04, hms03, hm...

Despite the interest that avian brood parasites provoke due to their reproductive strategy, and the wealth of published studies, their mating system is one of the least known aspects of their natural history. This study describes the first attempt to use genetics to characterize mating patterns in a brood parasite, the great spotted cuckoo (Clamator glandarius). We developed a set of microsatel...

BACKGROUND Polyandry is widespread throughout the animal kingdom. In the absence of direct benefits of mating with different males, the underlying basis for polyandry is enigmatic because it can carry considerable costs such as elevated exposure to sexual diseases, physical injury or other direct fitness costs. Such costs may be balanced by indirect genetic benefits to the offspring of polyandr...
