    Opis:
    The aim of this article is to highlight the achievements of human behavioural genetics. It begins with a brief overview of the field of contemporary human behaviour genetics. Then, the general principles of behavioural genetics, research methods used, the concept of heritability and areas of rapid advancement in the field are identified. While classical twin studies have been a powerful tool to find heritability or the genetic correlation between different human behaviours, new tools are now available to help identify the genes responsible for individual differences. In particular, association studies and DNA methylation studies are crucial to advancing knowledge on the genetic basis of human behaviour as well as on the epigenetic factors that mediate genetic and environmental effects on behaviour. Several results on the heritability of human behaviour, relationships between genetic polymorphisms and behaviour as well as the consequences of DNA methylation are reported in this article.

    Opis:
    Seed and seedling vigour is an aspect of seed quality which affects field establishment and performance. Low maize yields have been reported  to be affected by several factors in which poor quality seed with low seed and seedling vigour. Information is scarce on seed and seedling vigour in maize inbred lines developed for tropical environments. Fifteen genotypes of tropical maize (Zea mays L.) inbred lines were evaluated to determine the level of differences in seed and seedling vigour traits, and extent of relationships among traits and their heritability. A substantial amount of genetic variability was found, which suggested that most of the traits under study could be improved through selection and utilized in breeding programs. Positive and signifi- cant interrelationship  among  seed germination  and seedling  traits  and  a positive  correlation  between  seed germination and seed vigour and field emergence showed that these could be given due consideration in crop improvement for seed and seedling vigour. High genotypic coefficient of variation, heritability and genetic advance were obtained for seed germination, seed emergence, shoot length and seedling vigour index I and II, revealing the possibility of improvement in these characters through direct selection. The principal component analysis (PCA) identified seed emergence, shoot length, seedling vigour index I and II and tetrazolium vigour as characters that contributed greatly to variation in seed vigour in the maize inbred lines. Cluster analysis partitioned the genotypes into two groups, with group I consisting of seven genotypes and group II comprised the other eight genotypes, which suggested that hybridization between the two groups could lead to high level of heterosis. Genotype V5  had superior seedling vigour traits compared to other genotypes. Seedling emer- gence, shoot length, seedling vigour index I, seedling vigour index II and tetrazolium vigour are effective characters for good seedling vigour traits in maize inbred lines investigated.

    Opis:
    Four different protein families (two proteinase inhibitor families, myoglobins and lysozymes) were surveyed for correlated mutations with respect to the position distance and their significance in structure stabilization and biological activity. They were chosen for this study in order to verify the currently admitted model of mutational correlation relationship with respect to spatial contact of the residues and contribution in protein biological activity. There was observed high contribution of spatially dispersed residues (which are also not involved in the protein active center) in mutational correlation. Because of the significantly large distance between correlated positions these cases do not correspond explicitly to any mechanism included in current hypotheses. It is suggested that the role of residue spatial contact in structure preservation, intermolecular interaction and active site rescue mechanisms only partially explains the correlation phenomenon.
