In a hybrid zone, the process of 'reinforcement' leads to which of the following outcomes?

  • option_A: Strengthening of prezygotic barriers, decreasing the formation of unfit hybrids.
  • option_B: Weakening of reproductive barriers, leading to the fusion of parent species' gene pools.
  • option_C: Maintaining a stable hybrid zone with continuous production of mixed ancestry offspring.
  • option_D: Increased gene flow between the two parent species, promoting hybridization.

Explanation

The text states: 'In others, reinforcement strengthens prezygotic barriers to reproduction, thus decreasing the formation of unfit hybrids.'
