The role of sex chromosomes in speciation in the two European nightingale species (GP206/08/P160)

A prominent role of sex chromosomes in speciation represents one of the most is to examine the role of sex chromosomes in speciation in birds, a group in which females mechanisms of speciation is based on ...

The genetic basis of species origin What can we learn from organisms with female heterogamety? (GA18-14325S)

A large effect of sex chromosomes in speciation belongs to the most general chromosomes). Here we propose to study the role of sex chromosomes in speciation in taxa of sex chromosomes in this proc...

Chromosome rearrangements in the evolution of moths and butteflies (Lepidoptera) (GA17-17211S)

distinct hosts and thus can be in general attributed to speciation with gene flow that chromosome rearrangemnts such as inversions can restrict recombination and thus promote speciation. Yet supporting empirical evidence s...

Turnover of sex chromosomes in the karyotype evolution of Lepidoptera (GA14-22765S)

Sex chromosomes are special parts of the genome playing an important role in ecological adaptation and speciation. This also applies to Lepidoptera, a speciose insect chromosome constitution, Z0/ZZ (female/male), whereas th...

Germline restricted chromosome in songbirds understanding its origin, function and evolutionary significance (GA20-23794S)

In songbirds, an extra chromosome exists in the germinal cells. This so-called germline restricted chromosome (GRC) is inherited only through females and early during. Although the GRC represents the largest chromosome in m...
