In batesian mimicry, one species resembles another, poisonous species.
I. Poisonous species is more common than mimic
II. Poisonous species is present in same area as mimic
III. Poisonous species competes for resources with mimic
IV. Poisonous species is distinctly or brightly colored

The effectiveness of batesian mimicry can be increased by

• A. I and II
• B. I, II and III
• C. I, II and IV
• D. II, III and IV
• E. I, II, III and IV

Answer 1

The correct option is C I, II and IV

Batesian mimicry refers to the resemblance of a harmless or palatable species with that of a dangerous or unpalatable one to make predators avoid them. A more common and distinct poisonous species present in the same area as mimic become familiar to predators of mimic and thereby increase the effectiveness of mimicry. Competition between mimic and poisonous species would harm either of them while mimicry is an adaptation for the protection of mimic. Thus, the correct answer is option C.
