Genotypes are frequently used to identify parentage. Such analysis is notoriously vulnerable to genotyping error, and there is ongoing debate regarding how to solve this problem. Many scientists have used the computer program CERVUS to estimate parentage, and have taken advantage of its option to allow for genotyping error. In this study, we show that the likelihood equations used by versions 1...

Nine loci have been compiled into two multiplex microsatellite polymerase chain reaction (PCR) sets (four and five loci) and used as a tool to determine the most probable hind for each calf. The two sets were suitable to combine them in an eight-plex reaction. The exclusion probabilities of the eight-plex reaction and the nine loci were 99.3 and 99.6 % respectively, which allows the routine app...

A total of 45 blood samples from progeny and the putative parents were tested for parentage analysis using a panel of microsatellite markers (short tandem repeats). Six breeds of dogs were represented viz. German shepherd, Dalmatian, Labrador, Great Dane, Boxer and Lhasa Apso in this study for genotype analysis. Ten different microsatellite marker loci were amplified by multiplex PCR. The multi...

The main objective of this study was to verify the association between the coefficient of parentage estimates and multivariate techniques which were used as measures of genetic diversity in cultivars. Thirty cotton cultivars were used for this purpose among which genetic diversity was estimated by means of the parentage coefficient (CP) and also through multivariate techniques employing microsa...

Parents of a variety of animal species distribute critical resources among their offspring according to the intensity of begging displays. Kin selection theory predicts that offspring behave more selfishly in monopolizing parental care as relatedness with competitors declines. We cross-fostered two eggs between barn swallow (Hirundo rustica) clutches and compared the loudness of begging between...

Singlet electronic excitations of DNA duplex trimers and tetramers with regular homogeneous base-pair sequences ((dA)n.(dT)n and (dG)n.(dC)n, with n=3, 4) have been investigated in vacuo using semiempirical quantum chemistry in a Zerner's Intermediate Neglect of Differential Overlap (ZINDO) approximation. Frequencies, oscillator strengths, and single-electron assignments of many-electron transi...
