Opis:: A haplotype analysis is becoming increasingly important in studying complex genetic diseases. Various algorithms and specialized computer software have been developed to statistically estimate haplotype frequencies from marker phenotypes in unrelated individuals. However, currently there are very few empirical reports on the performance of the methods for the recovery of haplotype frequencies. One of the most widely used methods of haplotype reconstruction is the Maximum Likelihood method, employing the Expectation-Maximization (EM) algorithm. The aim of this study is to explore the variability of the EM estimates of the haplotype frequency for real data. We analyzed haplotypes at the BLM, WRN, RECQL and ATM genes with 8-14 biallelic markers per gene in 300 individuals. We also re-analyzed the data presented by Mano et al. (2002). We studied the convergence speed, the shape of the loglikelihood hypersurface, and the existence of local maxima, as well as their relations with heterozygosity, the linkage disequilibrium and departures from the Hardy-Weinberg equilibrium. Our study contributes to determining practical values for algorithm sensitivities.

Tytuł:: Bovine kappa-casein [CASK] gene - molecular nature and application in dairy cattle breeding
Autorzy:: Kaminski, S

Opis:: The bovine kappa-casein (CASK) gene is considered a potential marker for quantitative trait loci (QTL) in dairy cattle. A large amount of research has been performed to explore the nature and variation of the CASK gene and its possible applications in cattle breeding. The purpose of this review is to sum up the knowledge of all known aspects of the CASK gene: molecular structure and function, polymorphism and allele freqeuncy, methods of genotyping and possibilities of the use of CASK polymorphism in dairy cattle breeding.

Opis:: Plants were regenerated from immature embryo cultures of 35 winter wheat genotypes. General responses of regenerated plants were investigated and a total of 7142 R₂ spike lines from 1593 R₁ plants were assessed in the field for somaclonal variants in 1985/86, 1986/87 and 1987/88. Selected variants were studied for their possible genetic inheritance. From regenerated plantlets, 81% survived and 63% produced fertile plants. Forms with reduced plant height, length of spike and other morphological abnormalities were found in this progeny. Populations of R₁ plants were highly variable due mainly to the physiological disturbances resulting from the in vitro process. Overall somaclonal variation frequencies were 14.2% per plant basis and 5.3% per R₂ spike basis. The variants were similar in the three different R₂ generations with predominant variants being negative in plant height, maturity, awns, spike type and plant type. Both uniform R₂ variant families and spike lines were found in addition to the segregating variants which constituted the majority. On average, in a variant family or line, 18% and 14% of their component lines and plants were variants, respectively. Inheritability was demonstrated for the uniform variant families and spike lines as well as segregated variants. Of those 134 selections, about 70% were classified as inheritable. Both recessive and dominant gene mutations at one, two or three loci were evident in some variants as suggested by the segregating data.
