Answer: Ras activity would be significantly slower in its response to extracellular signals.
Explanation:
• GTPase acts as a catalyst in converting RasGTP (active state) to RasGDP (inactive state)
• A mutant lacking the GTPase activating protein cannot activate GTPase so thee will nit be any functional GTPase
• if GTPase is not present then RasGTP may be expdessed for longer periods of time and there will be a lag until it eventually switches "off)
The correct answer is stabilising selection. This is selection that favours an average trait value. It is thought that this sort of selection is very common as traits among most animals do not appear to change drastically over time. Stabilising selection selects against the extreme traits, and leads to a decrease in genetic diversity by favouring the average phenotypes.
