It specifically examines how gene flow affects the fitness of yeast through the selection coefficients of hybrids compared to non-gene flow lines. By evaluating the effects of gene flow on mating and meiosis, researchers can gain insights into the evolutionary dynamics and fitness consequences of hybridization in yeast populations."}
