Open Scied: Natural Selection Examples

1

An organism's traits are determined by its DNA

True

False

1

How many blue snakes are there in the population?

1

How many brown snakes are there in the population?

1

How many green snakes are there in the population?

1

Which color(s) of snakes are best suited for the environment grass and dirt environment?

Blue

Green

Brown

1

Which color of snake is more likely to be seen by predators?

Blue

Green

Brown

1

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

1

Due to the drought the environment is mostly brown dirt. Which color snake is "best fit" for the environment?

Brown

Green

1

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

1

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

An organism's traits are determined by its DNA

There are no genetic variations in populations

Variations or differences in individuals are due to mutations

In natural selection the organism with the best traits survive and reproduce

Organisms with "bad" traits can change their traits in order to survive
