Nonsense
Missense
Silent
No go amigo
All of the statements EXCEPT one are true about mutations. Which statement is false?
Mutations must be present in both parents and then passed to offspring.
Mutations can be positive and produce organisms with improved traits.
Mutations can be fatal to the organism that has a mutation, if the mutation is in a critical gene.
Mutations can be silent, and not affect the organism that has them, if the mutation is in a non-critical area.

Artificial Selection
What is natural selection?
inherited characteristic that increases chances of survival
organisms with traits well suited to their environment survive and reproduce at a greater rate
