Genetic parentage analyses provide insights into mating systems and have revealed widespread evidence for polyandry in natural populations. Here, we use 5 microsatellite markers to estimate female mating rates in a feral population of green swordtails, Xiphophorus helleri, a live-bearing poeciliid fish that has become a model system in the study of precopulatory mate choice and mating competiti...

Genetic analysis of avian mating systems has revealed that more than 70% of monogamous species show incidence of offspring parentage that does not match the social partner. Extra-pair parentage (EPP) has been linked to a variety of factors, including size and symmetry of ornamental traits, coloration, resource availability, and local conspecific density. We examined how ornamental plumage trait...

Single nucleotide polymorphisms (SNPs) are plentiful in most genomes and amenable to high throughput genotyping, but they are not yet popular for parentage or paternity analysis. The markers are bi-allelic, so individually they contain little information about parentage, and in nonmodel organisms the process of identifying large numbers of unlinked SNPs can be daunting. We explore the possibili...

A study was conducted to assess the feasibility of applying a panel of 10 microsatellite markers in parentage control of beef cattle in Portugal. In the first stage, DNA samples were collected from 475 randomly selected animals of the Charolais, Limousin and Preta breeds. Across breeds and genetic markers, means for average number of alleles, effective number of alleles, expected heterozygosity...

A set of 233 Holstein calves, their 233 dams and 44 sires from 4 large-sized herds was genotyped for 10 microsatellites recommended by ISAG for paternity/parentage testing. Heterozygosity of microsatellites ranged from 0.607 (SPS115) to 0.835 (TGLA227), and PIC from 0.575 (SPS115) to 0.816 (TGLA227) confirming a high polymorphism of each analysed locus. Their combined exclusion probability reac...

for identification of individuals and parentage control performed by cattle breeders in the czech republic, a novel finnish bovine genotypes™ panel 3.1was amplified by means of one multiplex polymerase chain reaction. bovine panel encompasses all the 12 str loci recommended by the international society for animal genetics (isag) for routine use in parentage testing and identification, including...
