Which of the following is NOT an outcome predicted by Lotka–Volterra competition model?

The keyed exception is “Species hybridization.” In the context of which of the following is not an outcome predicted by lotka–volterra competition model, that statement differs from the governing ecological pattern and must be evaluated against the mechanism rather than accepted from wording alone. Coexistence requires stabilizing differences that make each species limit itself more strongly than it limits its competitor, or an equalizing process that keeps fitness differences small. Without such mechanisms, persistent competitive asymmetry tends toward exclusion. The remaining alternatives—“S

What happens when α12 = 1 and α21 = 1, and K1 = K2?

“Unstable coexistence” for what happens when α12 = 1 and α21 = 1, and k1 = k2. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. Coexistence requires stabilizing differences that make each species limit itself more strongly than it limits its competitor, or an equalizing process that keeps fitness differences small. Without such mechanisms, persistent competitive asymmetry tends toward exclusion. The remaining alternatives—“Mutualism”, “Stable coexistence”, “Species 1 wins”—refer to different states
