Development of Meta-Server for Prediction of Mutations Effects on Protein Function
Lisák, Peter ; Burgetová, Ivana (referee) ; Jaša, Petr (advisor)
This bachelor thesis deals with analysis of genomic data, more specifically prediction of effects of mutations on protein function using a protein sequence or tertiary structure. The theoretical introduction describes the basics of genetics and bioinformatics and is followed by description of selected prediction tools such as SIFT, MAPP and AUTO-MUTE. A unified interface for work with different tools is proposed in the thesis. The meta-server interface allows running a computation and collecting results from one site. meta-server combines results of implemented tools and provides a consensual prediction, which is expected to be more accurate than the results from individual tools. Finally, testing of meta-server on the real data and comparisons of predictions with the experimentally obtained results are presented.

Genetická a morfologická variabilita skupiny \kur{Melampyrum nemorosum}
DRAHNÍK, Petr
Melampyrum nemorosum agg. is very complicated group of hemiparasitic plants. According to the traditional concept, 15 species is distinguished. Recent molecular analyses show a need of critical taxonomic revision of group and a potential importance of ancient hybridization. Analysis of 3 regions of cpDNA (trnTUGU-trnLUAA, psbA-trnHGUG, rpl32-trnLUAG) and 2 regions of nuclear DNA (Agt1 and At103) reveals well supported lineage with limited geographical distribution. Morphology and genome size of genetically supported lineages were compared.

Genetic variability of dung beetles on pastures.
VRBOVÁ, Kristýna
The aim of this thesis was a research of the genetic variability of 8 populations of the dung beetle Aphodius prodromus using allozyme markers. Following population-genetic analysis were used to determine genetic structure of these populations: estimates of heterozygosity, Wright´s F- statistics, estimates of gene flow, Mantel test, PCA, Nei´s genetic distance, testing of Hardy-Weinberg equilibrium and linkage disequilibrium. The results revealed low gene flow between populations, low number of heterozygotes and disequilibrium within and between populations. Cluster analyses showed, that populations from Tichá and Rychnov nad Malší-hřbitov are genetically most different from other populations.

Morphological types of selected valleys in the High Sudetes
Košíková, Karin ; Křížek, Marek (advisor) ; Štěpančíková, Petra (referee)
Valley is a place, where the record about processes realizing upstream and downstream is deposited. It's valuable source of information about the evolution of landscape around. The Bachelor thesis is focused on creating the genetic classification of valleys, where the evolution and shape were described, then some characteristics useful for studying longitudinal profile were set also. Studies of metrics were performed in GIS. Main interest was attended to lengths, widths and shapes of valleys of Králický Sněžník mountains. Correlation matrix of parameters and dendrogram, which was used to delimit four clusters, were created. Through this Bachelor thesis, where more komplex analysis was used, good applicability of used metrics was shown. This method could be used in Králický Sněžník mountains and in future it could be aplicated in different localities also. Keywords: valley, genetic typology, longitudinal profile, Králický Sněžník mountains

Forensic investigation and economic crime
Švajnochová, Gabriela ; Müllerová, Libuše (advisor) ; Hótová, Renáta (referee)
Topic of this master thesis is forensic investigation and forms of economic crime which can be detected during the investigation. First chapter focuses on forensic investigation and its comparison with statutory audit. In the second chapter is performed analysis of forms of economic crime in the Czech Republic, Southern and Eastern Europe and globally. Knowledge from the previous chapters is applied to the real forensic investigation performed in the Czech Republic, forensic investigation of project OpenCard.

Analysis of selected genomic regions with dominant suppressors of the \kur{adgf-a} mutant phenotype in \kur{Drosophila melanogaster}
KADLECOVÁ, Jana
Adenosine is an important signaling molecule in various physiological processes in many different organisms. Dysregulation of the level of this molecule leads to many pathological consequences as Severe Combined Immunodeficiency in humans. Recently a genetic model using fruit fly Drosophila melanogaster was established to study effects of adenosine in this organism and a genetic screen for genes modifying the effects of heightened adenosine was started. This work presents partial tasks in this screen which include detailed characterization of selected regions which were identified as dominant suppressors of the phenotype associated with heightened adenosine. First task was to produce a smaller, molecularly defined deletion in range of originally identified bigger deletion. Second task included a testing of already existing smaller deletion for the suppressing effects. In the third task, a role of potential suppressor was further analyzed which included a verification of P-element insertions in this gene and their testing for suppressing effects. In the last task, the sequence for making a probe to characterize the expression of this gene was cloned

Interspecific hybridization in Acrocephalus warblers.
Majerová, Veronika ; Reifová, Radka (advisor) ; Kotlík, Petr (referee)
Acrocephalus warblers have gone through the adaptive radiation during last severalmillion years, which gave rise to thirty one species occupying mainly Eurasia,Africa and Australia. The majority of species are morphologically very similar,however, they differ in ecological requirements, migration strategy, and song.Interspecific hybridization seems to be quite common among Acrocephaluswarblers, not only between sister species, but also between more distantly relatedtaxa. The main goal of this study was to determine whether this hybridization leadsto gene flow between species and which factors affect the rate of interspecific geneflow. For this purpose we conducted population-genetic analysis in three Europeanspecies of the Acrocephalus warblers of the subgenus Notiocichla: reed warbler (A.scirpaceus), marsh warbler (A. palustris), and blyth's reed warbler (A. dumetorum).Our results based on the analysis of sequence data from eight nuclear loci indicate,that gene flow between the studied species occurs, but only in one direction. Thegene flow is higher between genetically more related species than betweenecologically more similar species. We also estimated that the reed warbler and themarsh warbler diverged approximately 1,1 million years ago. The blyth's warblerand ancestor of the reed and marsh warbler...
