Seventy-seven cases of disputed parentage were studied using the human leucocyte antigen system over a 14-year period in Hong Kong. Of these, 30 (39.0%) related to the amendment or verification of birth registration details, 20 (26.0%) were for divorce or affiliation proceedings, and 19 (24.7%) were related to overseas resident visa applications. An exclusion of parentage of at least one of the...

Brazilian goats are generally kept in small herds and extensive rearing systems, mainly in the northeastern region of the country. Despite production improvement in recent years, the lack of pedigree control has affected genetic progress. This study aimed to validate a panel of 16 microsatellites for parentage testing in locally adapted and commercial goats breeds raised in Brazil, as well as t...

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 ...

Short tandem repeat (STR) loci, i.e. microsatellites are a class of genetic markers commonly used for population studies and parentage control. This study determined the usefulness of microsatellite markers recommended by International Society for Animal Genetics (ISAG) for identification and pedigree analysis in horses based on the example of Polish Hucul horse population (Equus caballus). The...

The demand for glycine to satisfy normal growth during early life is considerable and most has to be made endogenously. The extent to which adequate glycine is available can be assessed by measuring the urinary excretion of 5-L-oxoproline. The excretion of 5-L-oxoproline at 6 weeks of age for infants in Trinidad of African, Indian or mixed parentage (398 mumol/mmol creatinine) was significantly...

Since the middle of the 1990s, parentage assignment using microsatellite markers has been introduced as a tool in aquaculture breeding. It now allows close to 100% assignment success, and offered new ways to develop aquaculture breeding using mixed family designs in commercial conditions. Its main achievements are the knowledge and control of family representation and inbreeding, especially in ...

The fractional parentage expansion method is extended from SU(2) nonrelativistic to SU(3) and relativistic dibaryon calculations. A transformation table between physical bases and symmetry bases for the SU (3) dibaryon is provided. A program package is written for dibaryon calculation based on the fractional parentage expansion method.

Question: What is the adaptive significance of extra-pair parentage? Theoretical approach:We view parentage as a ‘transaction currency’ for exchanges of ecological benefits. We develop a multi-player cooperative game, using the core and the Nash bargaining solution as solution concepts. Model assumptions: Birds can negotiate about who pairs with whom. Parentage can be exchanged between individu...

Haplodiploidy results in relatedness asymmetries between colony members of highly eusocial Hymenoptera. As a consequence, queen and reproductive workers are more related to their own sons than to each other's male offspring. Kin selection theory predicts multiple optima in male parentage: either the queen or the workers should produce all the males. Nevertheless, shared male parentage is common...
