If a person has a dominant allele for attached earlobe and a recessive gene for detached earlobes, what kind of earlobes will they have?
What is attached
200
What is gene flow
What is the process of genes moving from one population to another
200
The process of the organisms with the greatest fitness for their environment surviving and passing on their traits
What is natural selection
200
When new species are formed in the same geographic area this is known as ___________________ speciation
What is sympatric
200
This type of evolution happens at slow steady rates
What is gradualsim
300
Different forms of the same gene are called
What is alleles
300
A mistake in the copying of the genetic code
What is a mutation
300
This type of selection favors the most average in a population
What is stabilizing
300
Prezygotic barriers are reproductive barriers that occur ____________________ fertilization
What is before
300
This scenario refers to a population that is not evolving
What is the hardy weinberg equilibrium
400
What are 2 factors that cause genetic variation in a population
What is mutations, shuffling of genes in gamete formation, random pairing of egg and sperm
400
What is genetic drift
What is when the alleles of a population change due to random events
400
This type of selection favors one type of extreme of a trait
What is directional
400
When evolution occurs at quick irregular intervals
What is punctuated equilibrium
400
This type of isolation causes sympatric speciation
What is reproductive isolation
500
The term given to the change of a population on a genetic level
What is microevolution
500
What are the 5 ways a population can evolve
What is mutations, gene flow, genetic drift, nonrandom mating, natural selection

The name given to the shape of a graph for a particular trait in a population
What is tghe bell curve
500
When species are classified according to physical appearance
What is morphology
500
This type of selection favors the extremes of a trait
What is disruptive selection
