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

Back

Because they are more likely to survive and reproduce.

According to natural selection, light colored tree trunks would favor:

light colored moths

,

dark colored moths

,

red colored moths

,

red and light colored moths

Back

light colored moths

Speciation can occur as a result of geographic isolation because:

Back

populations that live in different environments may be exposed to different selection pressures

The trees these moths used to live on were white, but have been covered in soot from coal factories. Which moth will be more successful in this environment? Options: Dark moth, Light moth, Both will be equally successful, Neither will be successful

Back

Dark moth
