Essential Questions
You will be able to answer:
How is genetic information expressed in physical traits?
How does variation arise in populations?
The Learning Goals:
I can use Punnett Squares to explain the variation and distribution of expressed traits in a population.
I can analyze data to find evidence that organisms with advantageous traits increase in populations relative to organisms without those traits.
