Question

Many insects have a “lock and key” type of genitalia in which the male reproductive structures will only fit into the reproductive structures of females of the same species so that even very similar species will not be able to mate with one another. Therefore you would only expect to find sperm of the correct species in the reproductive tract of a female. What properties would you expect to see in the eggs of this insect?

Group of answer choices

A. very specific species specific recognition proteins on the egg and a fast block to polyspermy

B. very specific species specific recognition proteins on the egg and no fast block to polyspermy

C. less specific recognition proteins on the egg and a fast block to polyspermy

D. less species specific recognition proteins on the egg and no fast block to polyspermy

E. asexual reproduction
