Question

1.) The Giant Sequoia is a monoecious spe cies, which means eàch individual tree produces male and female gametes. In other words, you can find male cones (pollen-producing) and female cones (ovule-producing) on the same tree a.) From Darwin's perspective on evolution, why would this present a problem for selection and maintenance of "fitness?" (2 pts) b.) Although they are generally used to describe their role between species, which reproductive isolating mechanism might be effective in preventing the Giant Sequoia from self-fertilizing? Include how it works as well. (2 pts) c.) What might prevent the production of a hybrid species (a cross between two species) if pollen from a nearby pine tree were to reach the ovule of a Giant Sequoia. (1 pt)
