1. The genomic basis of the response to female-limited X-chromosome evolution
Sammanfattning : In this thesis, I attempted to achieve a better understanding of the nature of X-linked polymorphic loci using a female-limited X chromosome (FLX) experimental evolution in Drosophila melanogaster. I expected that expressing the evolved X chromosome will result in an increase in female fitness and a decrease in male fitness. LÄS MER
2. Molecular architecture of meiotic chromosomes
Sammanfattning : Faithful chromosome segregation at each cell division is essential as the formation of cells with an abnormal number of chromosomes (aneuploid cells) can result in infertility, developmental defects or cancer. Aneuploidy occurs in approximately 20% of all conceptions, causing infertility and embryo death. LÄS MER
3. BEN-solo proteins in genome architecture and function
Sammanfattning : Eukaryotic genomes are organized in a complex manner inside the nucleus of each cell. Chromatin insulators are DNA elements that help to fold the linear DNA fiber in three-dimensional space and partition regulatory gene units. LÄS MER
4. Exploring the multiscale 3D architecture of human chromosome contact networks
Sammanfattning : Cells regulate genes to coordinate essential functions allowing cells to grow, divide, specialize, and respond to stresses. While regulatory proteins are the most common way to control these genes, the DNA’s 3D structure also plays a critical role as it affects how proteins access genes and how regulatory DNA elements interact over large genomic distances.

5. The genetic architecture of sexual dimorphism
Sammanfattning : Phenotypic differences between the sexes evolve largely because selection favours a different complement of traits in either sex. Theory suggests that, despite its frequency, sexual dimorphism should be generally constrained from evolving because the sexes share much of their genome. LÄS MER
