How does sexual reproduction help to keep a species healthy?

How could a harmful trait continue to be carried through many generations of an organism?

• If it forms in a body cell it can be replaced.

An overgrowth of organisms like bacteria happen very quickly compared to an overpopulation of an animal like a rabbit. Which explanation best explains why this happens?

• Rabbits reproduce sexually, which results in a lot of deaths in the population.

• Bacteria reproduce asexually, which is a much faster way to reproduce than sexual reproduction.

• Sexual reproduction only involves one parent so it is less complicated.

• Asexual reproduction in rabbits is limited to the production of only one kind of cell.

A spider plant is a popular house plant, partly because they are hard to kill. They send out a lot of "baby" plants that put out their own roots and can exist independently of the parent plant. However, spider plants also produce flowers and seeds. Which explanation best describes the methods of reproduction in this kind of plant?

• They reproduce by budding because they pinch off baby plants.

• Flowers begin as buds so this is a form of asexual reproduction.

• Spider plants produce both sexually and asexually.

• Larger organisms like a spider plant only reproduce sexually.
