How Strawberries are helping us extend Mendelian genetics

Organisms with multiple sets of chromosomes must balance their gene expression levels to survive. By analyzing dominance patterns and chromatin accessibility in strawberries, Fang et al. described the mechanism of subgenome dominance that allows strawberries and other allopolyploid species to survive.  This webpage was produced as an assignment for an undergraduate course at Davidson College. …

Neanderthals, Denisovans, and Homo sapiens cohabited in Europe 45,000 years ago. So, why are we the only remaining ones?

About the author: Nicolas Pinzon A genomic and anthropological collaborative study of a cave in Germany shows that Homo sapiens habited northern European lands 45,000 years ago; far before the extinction of Neanderthals. This proves…
