What adaptation does not increase the chances of fertilization in gymnosperms?

• Pollen from male cone can be carried by the wind

• The ovule seals.

• female cone has a sticky substance

• seeds develop inside the fruit

An advantage of pheromones is

• it warns other species to stay away

• it sends a message that an individual is ready to mate

• it expresses dominance and mating interest.
