Question

How does selective breeding help corals become more tolerant of warm temperatures?
By introducing warmth-tolerance genes
By increasing the acidity of the water
C By decreasing the algae levels
By making the corals smaller in size

Answer 1

Selective breeding helps corals become more tolerant of warm temperatures primarily **by introducing warmth-tolerance genes**. Through selective breeding, researchers can identify and propagate coral individuals that exhibit traits that permit them to thrive in higher temperatures, enhancing the resilience of coral populations to climate change and ocean warming. The other options provided do not accurately relate to the mechanisms of selective breeding for enhancing coral heat tolerance.
