Mechanistic insight into genomic exclusion
Hybridogenesis is an unusual form of reproduction that combines elements from asexual and sexual reproduction. It usually takes place in organisms that are hybrids of other species and involves the selective transmission of one of the parental genomes to future generations. The key objective of the EU-funded SEXY project is to understand the molecular mechanism of selective genomic exclusion. Researchers will employ Bacillus stick insects as a model system and study potential genomic loci and maternal factors that may impact the process of genomic exclusion. Results will help understand how the intriguing process of hybridogenesis has evolved in certain species.
