Abstract

The ease in genome sequencing nowadays is increasing the number of studies in several research fields, e.g. molecular evolution and comparative genomics. However, despite the availability of many new genomes every year, theoretical studies are necessary to correctly explore this data. In this context, this project is designed to determine the best approaches while analyzing comparative genomics data. To delineate these best approaches we will employ both simulated and empirical data from Insecta and other taxonomic groups. The project is subdivided in three different topics corresponding to three different common comparative genomics analysis. In the first we will determine the influence of distinct evolutionary rate (É) parameter values in PAML's likelihood ratio test results. In the second we will infer convergent and parallel substitutions along random sets of species to determine the patterns of these substitutions along the genomes of independently evolved lineages. In the third we will determine the influence of distinct divergence time estimations on analysis of gene families evolution. At the end of this project we expect to determine and provide the best approaches to be used in large-scale comparative genomic studies, such as the genetic basis for the hematophagy evolution in Insecta.
