Final answer:
The statement 'In sexual reproduction, the egg is the limiting resource that results in choosy males' is false. Instead, studies have shown that in certain cases, sperm can be a limiting resource, influencing male mating behavior.
Step-by-step explanation:
Research on male fruit flies demonstrated that sperm-depleted males, or those with a lower supply of sperm due to previous matings, were more selective and tended to mate with larger, more fecund females. This selective behavior by males with a limited amount of sperm ensures that they maximize their reproductive success by choosing partners likely to produce more offspring.
This mating behavior is significant as it reflects how the physiological state of males can affect their reproductive choices and the strategic use of their reproductive resources to ensure the passing of their genes to future generations.
