Final answer:

The statement in the question is false; when the combined effect of hormones is greater than their individual effects, it is called a synergistic effect, not a permissive effect.

Step-by-step explanation:

If the effect of two or more hormones acting together is greater than the sum of each acting alone, the two hormones are said to have a synergistic effect, not a permissive effect. The statement given in the question is therefore False. A permissive effect occurs when the presence of one hormone enables another to act.

An example is the permissive relationship between thyroid hormones and certain reproductive hormones. In contrast, a synergistic effect occurs when hormones act together to create a greater effect than they would separately, like FSH and estrogens in the maturation of female ova.
