During the last decades, breeding has been supported by an increasing number of tools providing molecular genetic information. These tools may be based on the neutral variation inside the dog genome (parentage testing, breed assignation, estimation of genetic variability between and within breeds and individuals) or target functional variation (genetic test identifying carriers of inherited dis...

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...

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...

Overlapping offspring occurs when eggs are laid in a nest containing offspring from earlier reproduction. Earlier studies showed that the parentage is not always obvious due to difficulties in field observation and/or alternative breeding tactics. To unveil the parentage between overlapping offspring and parents is critical in understanding oviposition site selection and the reproductive strate...

Statistical tests that detect and measure deviation from the Hardy-Weinberg equilibrium (HWE) have been devised but are limited when testing for deviation at multiallelic DNA loci is attempted. Here we present the full Bayesian significance test (FBST) for the HWE. This test depends neither on asymptotic results nor on the number of possible alleles for the particular locus being evaluated. The...
