• Asexual reproduction needs only a female.

• The offspring are identical to the parent and to each other. They are known as clones.

• Asexual reproduction is more common in plants than in animal. For example, potatoes and strawberries can both reproduce asexually.

• The main advantage of asexual reproduction is that it is a very efficient method of reproducing large numbers of the species when conditions ( i.e. food and space) are available. Also, no time or energy is wasted looking for a mate. 

• Sexual reproduction requires two parents.

• The offspring produced by sexual reproduction are similar, but not identical to the parents.

• This variation is the main advantage of sexual reproduction. 

• The offspring are a combination of characteristics of the parents. This means a few of the offspring may be better suited to survive in their habitat, meaning the species can become more successful over time.

• Most organisms reproduce sexually. The benefits of producing offspring that show variation outweigh the costs of finding a mate, breeding, and producing the offspring.

• The music is quite loud.
