As climate change causes increased sand temperatures, we would expect to see a significant shift in the distribution of sea turtle offspring towards a predominance of female turtles. This change would primarily be an environmental effect rather than a genetic adaptation or mutation, as it is directly linked to the temperature-dependent sex determination system of sea turtles. Over time, if warmer temperatures persist, the imbalance in sex ratios may threaten population viability, leading to potential challenges in reproduction for future generations.
The sex of sea turtle offspring is determined by the temperature of the sand during development. Temperature over 87° Fahrenheit will result in female offspring. Temperatures below 87° Fahrenheit will result in male offspring. Scientists are concerned about the effects of climate change on sea turtle development. One of these effects is the warming of environments.
In 2-5 sentences, describe what change you'd expect to see in the distribution of sea turtle traits over time, if any. Explain whether it would be caused by a genetic adaptation, a mutation, or the environment.
