What information can you gain from this histogram?
The population has high distribution
The population has low variation
The population has high variation
The population has no variation
What can you tell about this population of Thornpalms from the histogram?
High water storage is an adaptive trait
It has a non-adaptive trait
It has medium to high variation
It has low variation
What can you tell about this population of newts from the histogram
Most of the newts have high poison levels
Most of the newts have medium poison levels
Low poison level is the adaptive trait
You cannot tell anything about the poison levels
Where do the genes that determine an individual's traits come from?
An individual can be born with any genes, since genes are random.
Individuals grow genes specific to their environment.
Parents pass their genes down to their offspring.
Parents choose which genes their offspring have when each individual is born.
How can an individual be born with an adaptive trait?
The individual can choose to change to the adaptive trait when they want to.
The parents had genes for the adaptive trait, which they passed down to the individual.
The individual can choose to have the adaptive trait at birth.
The parents can choose for the offspring to have genes for the adaptive trait.
