Mutations can be...
beneficial (good)
harmful
neutral
all of these
Organisms with the most adaptive traits surviving, reproducing, and passing on their traits is called
artificial selection
natural selection
breeding
gene modification
The amount of differences in traits in a population is referred to as
variation
mutations
natural selection
artificial selection
Which histogram shows HIGHER variation for spot size? LOOK CAREFULLY!
Population in brazil
population in venezuela
no way to tell
they both have the same
Why do non-adaptive traits not get passed on in populations as much as adaptive traits?
Individuals with non-adaptive traits choose not to reproduce
Individuals with non-adaptive traits reproduce less because they don't survive as long
Individuals with non-adaptive traits pass on their traits at the same rate
individuals with non-adaptive traits are unique and cannot pass on traits
Mutations happen ....
Randomly

when an organism wants to change
only to certain individuals
True or false:
HAving more genetic variation in a population makes that population healthier
true
false
