Question

How does selective breeding help corals become more tolerant of warm temperatures?

By increasing the acidity of the water
By making the corals smaller in size
By decreasing the algae levels
By introducing warmth-tolerance genes

Answer 1

Selective breeding helps corals become more tolerant of warm temperatures primarily **by introducing warmth-tolerance genes**. This process involves selecting and breeding coral specimens that exhibit a natural resilience to higher temperatures, promoting the propagation of their beneficial genetic traits. Over time, this can lead to a population of corals better adapted to withstand warmer water conditions, which is increasingly important in the context of climate change and ocean warming.
