An organism's traits are determined by its DNA
True
False
There are no genetic variations in populations
True
False
Variations or differences in individuals are due to mutations
True
False
In natural selection the organism with the best traits survive and reproduce
True
False
Organisms with "bad" traits can change their traits in order to survive
True
False
The blue snakes are most likely to be eaten by birds. What will happen to the blue allele (gene) in the population?
the blue allele (gene) will
increase
in the population
the blue allele (gene) will
decrease
in the population
the blue allele (gene) will stay the same
Due to the drought the environment is mostly brown dirt. Which color snake is "best fit" for the environment?
Brown
Green
What happened to the allele frequency of
green snakes
in the population?
the amount of green alleles (genes) increased
the amount of green alleles (genes) decreased
the amount of green alleles (genes) stayed the same
If there were no birds (aka the selective pressure) in the area, would there be a shift in the population to mostly brown snakes?
No
Yes
