Medium Summary
Wine grape varieties like Cabernet Sauvignon and Chardonnay have been genetically analysed using forensic DNA techniques to identify their parent strains. Cabernet Sauvignon is a cross between Cabernet Franc and Sauvignon Blanc, while Chardonnay originates from Pinot Noir and Gouais Blanc. This genetic knowledge aids in understanding grapevine evolution and could lead to genetically engineered grape varieties with improved qualities in the future.
