A gene pool consists of
all of the genes, including all the different alleles, that are present in a population
some of the genes, including the different alleles, that are present in a population
all of the genes that are present in all populations
all of the genes, including all the different alleles, that are present in all populations
The number of times a particular allele appears in a gene pool is known as the
population of the allele
relative percentage of the allele
frequency of the allele
evolution of the allele
Evolution can be defined as a ____________
change in the frequency of an allele in a population over time
change in the frequency of reproduction in a population
change in the frequency of an allele in an individual
Which of the following is NOT true about evolution?
Natural selection makes it happen
It happens equally across all species
Some individuals have a higher frequency than others
What do we a call an anatomical, physiological, or behavioral change that improves a populations ability to survive?
Adaptation
Coherent Change
Selective Breeding
Adamant Change
Which answer is more appropriate?
Traits are good or bad.
Traits can be harmful or hurtful depending on the environment.
Traits are always helpful or hurtful, regardless of the environment.
Traits are helpful or bad.
What does sunlight (UV exposure) do to folate in our body?
breaks it down
builds it up
creates it
makes it stronger
Why are advantageous traits more likely to be passed onto offspring?
Because the parents 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.
What process leads to a new species and often begins by a portion of a population become physically or geographically isolated?
Speciation
Selective breeding
genetic change
resistance
