Evolution Intro

What would happen to an organism's trait after years of natural selection against it?

• population would increase
• extinction
• variation
• population would stay the same

Farmers breed cows to produce high amounts of milk. This is an example of...

• Natural Selection 
• Variations in a species 
• Selective Breeding 
• inbreeding

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.

Inherited trait that helps an organism survive is a(n) __________.

• Fossil
• Adaptation
• Ancestor
• Natural selection

Mutations are important because they bring about

• death of the organism in which they develop
• genetic variation needed for a population to evolve
• benefits for the individual, not for the population
• Hardey-Weinberg equilibrium within a population

Genetic variation can arise from a random change in the DNA of a gene.  The change is called a(n)

• mutation
• gene flow
• gene pool
• allele

Genetic change over time is

• evolution
• generation
• growth
• biogenesis
