Artificial selection is another term for which of the following

• genetic engineering
• recombinant DNA
• selective breeding
• asexual reproduction

What is the main purpose for artificial selection

• to alter an organism's genetics  to produce more of a desired trait
• to prevent asexual reproduction
• to prevent problems from genetic engineering
• to ensure the longevity of the species

When dog breeders hybridize a new designer breed (such as labradoodle or puggle) through artificial selection what happens to the genetic information of the designer breed

• There are no changes to genes this can only happen with genetic engineering
• They can't produce designer breeds through natural selection.  You can only do this with genetic engineering
• Genes that are less desirable will become more common in the designer breed
• genes that produce desirable traits will become more common in the designer breed population

In a cross involving simple dominant and recessive traits what is needed for an organism to express the recessive trait

• 1 copy of the recessive gene
• 1 copy of the recessive gene from each parent (two total)
• One dominant and one recessive gene
• two dominant genes result in the recessive trait

What are the chances that two dogs with a recessive trait will pass the trait on to their offspring?

• 0%
• 25%
• 75%
• 100%

You observe an amoeba dividing to create two amoebas.  What can you infer about their genetic material (no mutations have occured)

• they will be 50% the same; 50% different
• Completely different
• 100% the same
• approximately 75% the same
