How could you test whether male dewlaps (a colourful flap of skin hanging from an anole lizard's throat)were an important cue for female egg production?

Question

Quizplus · Accepted Answer

The most appropriate test to determine whether male dewlaps are an important cue for female egg production is to remove the dewlaps from courting males and measure corresponding female egg production. This will isolate the effect of the male dewlap on female physiology and behavior. Removing dewlaps from females would not necessarily give an accurate measure of the dewlap's importance since females do not display their dewlaps during courtship. Relating size of male dewlap to female dewlap may provide some information on the relationship between male and female dewlaps, but it does not directly test whether male dewlaps influence female egg production. Therefore, option C is the best choice. Option D is incorrect because option A is not the most appropriate test.
