Estimating seed and pollen gene flow in plants on the basis of samples of naturally regenerated seedlings can provide much needed information about "realized gene flow," but seems to be one of the greatest challenges in plant population biology. Traditional parentage methods, because of their inability to discriminate between male and female parentage of seedlings, unless supported by uniparent...

BACKGROUND Nut-bearing trees, including oaks (Quercus spp.), are considered to be highly dispersal limited, leading to concerns about their ability to colonize new sites or migrate in response to climate change. However, estimating seed dispersal is challenging in species that are secondarily dispersed by animals, and differences in disperser abundance or behavior could lead to large spatio-tem...

Accurate pedigree information is critical to animal breeding systems to ensure the highest rate of genetic gain and management of inbreeding. The abundance of available genomic data, together with development of high throughput genotyping platforms, means that single nucleotide polymorphisms (SNPs) are now the DNA marker of choice for genomic selection studies. Furthermore the superior qualitie...

THE INTERPLAY BETWEEN GENETICS, PROCREATIVE INTENT, AND PARENTAL CONDUCT IN DETERMINING LEGAL PARENTAGE Deborah Wald, Esq., San Francisco, U.S.A. Our communities are increasingly populated with children for whom legal parentage is unclear. The three primary factors influencing legislative and judicial determinations of legal parentage tend to be: genetics, procreative intent, and parental condu...

Pedigree information and phenotypic records are the key features in animal genetics and breeding. Otherwise best methods for genetic evaluation and estimation of parameters will be tending to no correct results. This study was aimed to investigate and verify pedigree relations among 76 individuals who were genotyped for 3 fluorescent labeled microsatellite markers picked up from FAO-ISAG joint ...

Molecular parentage permits studies of selection and evolution in fecund species with cryptic mating systems, such as fish, amphibians, and insects. However, there exists no method for estimating the number of offspring that must be assigned parentage to achieve robust estimates of reproductive success when only a fraction of offspring can be sampled. We constructed a 2-stage model that first e...

Santa Inês is the most common hair sheep breed in Brazil and probably has the highest genetic diversity among sheep breeds in this country. Successful breeding programs for Brazilian sheep breeds are not common for various reasons, including a lack of control of parentage in the flocks. We developed an allele frequency database for 23 STR loci for the Santa Inês breed based on 285 animals ...
