Why are advantageous traits more likely to be passed onto offspring?

• Because they 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.

In a given population of plants there is variation in the time of day when flowers open. Those individual plants with flowers that open at night would be more likely to pass on this trait in an environment dominated by what?

Catfish have dorsal fin spines, which help defend against predators, and caudal fins, which help to propel the fish through the water. A swim bladder controls how high or low the fish sits in the water and gills allow the fish to breathe by taking oxygen out of the water. Catfish spend most of their lives at the bottom of freshwater lakes and streams. Which catfish trait may change (over many generations) if the pond habitat in which it lives becomes significantly deeper?

• Dorsal Fin

• Caudal Fin

• Swim Bladder

• Gills

Which of the following is required for a trait to become more common over time in a population?

• There must be many varieties of the trait in the population.

• The trait must allow members of the population to eat only some kinds of food.

• The trait must give individuals an advantage in producing offspring that survive.

• The trait must be the result of an immediate change in the environment.

Guppies are small fish that live in South American rivers. They can have different- sized spots on their bodies.

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 diagram below shows a population of guppies that live in a river. At time 1, the population had the same number of guppies with small and large spots. At time 2, after many generations, there were many more guppies with small spots and fewer guppies with large spots in the population.

How did the environment change between time 1 and time 2? How did the population change?

• You cannot tell how the environment changed. With each generation, more guppies passed on the gene for small spots to their offspring.

• The rocks became smaller. With each generation, more guppies with small spots survived long enough to pass on the gene for small spots to their offspring.

• The rocks became smaller. Guppies with small spots are more likely to survive, so the guppies with large spots changed to have small spots.

• The rocks became smaller. Guppies with small spots are more likely to survive, so both kinds of guppies passed on the gene for small spots to their offspring.

A fox with thicker fur than average would have a survival advantage over other foxes if:

• There is more competition for food in the fox population.

• The air temperature significantly decreases in winter.

• A drought occurs, limiting the amount of water available.

• A new disease appears that infects the foxes.
