Which prediction best shows what the population could look like after many generations? What caused it to change?

Prediction 1 is best. Two hummingbirds with short or medium beaks had a baby with a mutation in its genes for the long-beak trait. Because long-beak hummingbirds are more likely to survive, that baby survived long enough to pass on its mutation, so the long-beak trait became more common over generations.

Prediction 1 is best. Hummingbirds with long beaks are more likely to survive, so hummingbirds with short and medium beaks began to have offspring with a mutation in its genes for the long-beak trait so that their offspring would have a better chance to survive.

Prediction 2 is best. A hummingbird could have been born with a mutation in its genes for the long-beak trait and lived for a little while. Because long-break hummingbirds are more likely to die, it would have been more likely to die before it had any offspring, so the final population will only have medium or short beak hummingbirds.

Prediction 2 is best. A hummingbird could have been born with a mutation in its genes for the long-beak trait, but having a mutation in its genes would have caused it to die when it was born, so the final population will only have medium or short beak hummingbirds.

Which prediction best shows what the population could look like after many generations? What caused it to change?

Prediction 1 is best. Two seals with thick or medium blubber had a baby with a mutation in its genes for the thin trait. Because thin seals are more likely to survive, that baby survived long enough to pass on its mutation, so the thin trait became more common over generations.

Prediction 1 is best. Seals with thin blubber are more likely to survive, so seals with thick and medium blubber began to have offspring with a mutation in its genes for the thin trait, so that their offspring would have a better chance to survive.

Prediction 2 is best. A seal could have been born with a mutation in its genes for the thin trait and lived for a little while, but it would have been more likely to die before it had any offspring, so the final population will only have seals with thick or medium blubber.

Prediction 2 is best. A seal could have been born with a mutation in its genes for the thin trait, but having a mutation in its genes would have caused it to die when it was born, so the final population will only have seals with thick or medium blubber.

Guppies are small fish that live in South American rivers. They can have large spots, medium spots, or small spots. The river bottoms are covered in rocks. Guppies with spots that are the same size as the rocks on the bottom are harder for bigger fish to see and catch. The population of guppies shown lives in an environment that has always had large rocks. Could there ever have been guppies with small spots in this population?

A baby guppy could have been born with genes for the mutant small-spot trait and lived for a little while, but it would have died before it had any offspring.

No guppies could have been born with the small-spot trait because none of the adult guppies had that trait to pass down.

No guppies could have been born with the small-spot trait in the past, but some with that trait could be born in the future if the environment changes to have small rocks.

A baby guppy could have been born with genes for the mutant small-spot trait, but its mutant trait would have caused it to die when it was born.

Tree squirrels can have different fur colors. They can be black, brown, or gray. Squirrels live in forests where foxes also live. Foxes hunt squirrels for food. Squirrels that have fur the same color as the trees are harder for the foxes to see and catch. The population of squirrels shown above lives in an environment that has always had black trees. Could there ever have been squirrels with gray fur in this population?

A squirrel could have been born with a mutation in its genes for the gray trait and lived for a little while, but it would have been more likely to die before it had any offspring.

No squirrels could have been born with the gray trait because none of the adult squirrels had that trait to pass down.

No squirrels could have been born with the gray trait in the past, but some with that trait could be born in the future if the environment changes to have gray trees.

A squirrel could have been born with a mutation in its genes for the gray trait, but having a mutation in its genes would have caused it to die when it was born.
