Question

1. within the open ocean, many species of sea slug release gametes simultaneously, but eggs of each species cannot be fertilized by sperm of a different species. the type of evidence is 7. male fireflies signal to females of the same species by blinking their tail lights at a particular rhythm. females only respond to signals sent by males of their species. the type of evidence is

Explanation:

1. For question 6: This describes a reproductive barrier where gametes of different species cannot fuse, which is a type of prezygotic reproductive isolation evidence focused on gamete compatibility.
2. For question 7: This describes a species-specific mating signal and response, which is a prezygotic reproductive isolation evidence based on behavioral cues that prevent interspecies mating.

Answer:

1. Gametic isolation (prezygotic reproductive isolation evidence)
2. Behavioral isolation (prezygotic reproductive isolation evidence)
