Lectures of invited guests. Winter semester 2022:
25.-27.11.2022 The lectures start on Friday, 14:30, at the anthropology lecture room, Viničná 7, ground floor, near the hind staircase. Novel perspectives in speciation research and the role of non-Mendelian inheritance The lecture will present current advances in knowledge about the role of non-Mendelian reproductive systems in speciation and biodiversity formation. It will be organized into several blocks including theoretical as well as practical aspects of genomic and cytogenetic research on clonal and polyploid organisms. These will include:
1. Brief recap on current knowledge about speciation in the face of gene flow and the evolution of postzygotic reproductive barriers (the speciation continuum). What are the “species” and how do we define them?
2. Review of reproductive modes in Metazoans with particular focus on how non-Mendelian inheritance affects the interspecific gene flow.
3. Extended speciation continuum: a conceptual shift implementing the evolution of non-Mendelian inheritance into the speciation research. Emergence of clonally reproducing “species” and the evolution of polyploidy.
4. Cytogenetic methods to investigate mitotic and (mainly)meiotic chromosomes of (partially)clonal and polyploid organisms.
5. Genomic and transcriptomic methods to investigate genomes and gene expression in diploid and polyploid organisms of hybrid origin.
6. Population genomics of asexual organisms Speakers: Anatolie Marta, Mgr. – cytogenetics, chromosomal speciation Janko Karel, Mgr., PhD. – molecular ecology, genomics, transcriptomics Dmitrii Dedukh, Mgr., PhD. – molecular cytogenetics, meiosis
