variation and evolution

Why does sexual reproduction result in more genetic diversity than asexual reproduction?

• Characteristics from two parents are combined.

• More organisms reproduce this way.

• Offspring grow in different environments.

• Offspring come from identical parents.

• multicellular. 
• genetically varied. 
• genetically identical.

A plant that has traits(characteristics) identical to the parent plant provides evidence that the plant

• resulted from sexual reproduction.

• resulted from asexual reproduction.

• will develop many seeds.

• will have large leaves.

In order to grow two of the exact same plants, a person would reproduce them asexually because the

• genetic diversity is greater. 
• offspring would be genetically identical. 
• recessive traits would emerge. 
• negative traits are suppressed.

Why do frogs and other organism reproduce so many eggs or offspring?

• so that their babies can have friends to play with

• the more offspring the more likely some of the offspring will survive

• the more offspring the less likely offspring will survive

• the more offspring the less competition
