This paper investigates the effect of parents’ current income and long-term family characteristics on individuals’ highest educational qualification obtained by age 26 using UK data from the 1970 British Cohort Study. The issues of the possible sample selection bias produced by the not completely random omission of current family income and that of its potential endogeneity are addressed, using...

Moving towards the realization of genomic data in clinical practice, and following an individualized healthcare approach, the function and regulation of genes has to be deciphered and manifested. This is even more possible after the later advances in the area of molecular biology and biotechnology that have brought vast amount of invaluable data to the disposal of researchers. Two of the most s...

BACKGROUND The comparison of human related communication skills of socialized canids may help to understand the evolution and the epigenesis of gesture comprehension in humans. To reconcile previously contradicting views on the origin of dogs' outstanding performance in utilizing human gestures, we suggest that dog-wolf differences should be studied in a more complex way. METHODOLOGY/PRINCIPA...

In a previous paper, I investigated the interactions in a gene family of additive selection and biased gene conversion in a finite population when conversion events are rare. Here I extend my "weak-conversion limit" model by allowing biased interallelic conversion (conversion between alleles at the same locus) of arbitrary frequency and various threshold selection schemes for rare interlocus co...

Pentatricopeptide repeat (PPR) proteins compose a family of nuclear-encoded transcriptional regulators of cytoplasmic genes. They have shown dramatic expansion in copy number in plants, and although the functional importance of many remains unclear, a subset has been repeatedly implicated as nuclear restorers for cytoplasmic male sterility. Here we investigate the molecular population genetics ...

The paper presents application of data mining methods for recognizing the most significant genes and gene sequences (treated as features) stored in a dataset of gene expression microarray. The investigations are performed for autism data. Few chosen methods of feature selection have been applied and their results integrated in the final outcome. In this way we find the contents of small set of ...

A simple model of gene conversion presented earlier has been compared with a more general model under the assumption of no bias. The former is based on a simple concept that, by conversion, a gene (or a segment of a gene) is transferred from one locus to another in a multigene family. Intrachromatid symmetric conversion may result in reciprocal exchange of genes within a multigene family, and t...
