Biology Chapter 8: Mendel and Heredity
Standard:
Bd:
The student will demonstrate an understanding of the molecular basis of
heredity.
Indicators:
Bd.6:
Predict inherited traits by using the principles of Mendelian genetics (including
segregation, independent assortment, and dominance).
Bd.7:
Summarize the chromosome theory of inheritance and relate that theory to Gregor
Mendel’s principles of genetics.
Bd.8:
Compare the consequences of mutations in body cells with those in gametes.

Identify the investigator whose studies formed the basis of modern genetics
Describe the steps Mendel took in crossing his pea plants
Explain Mendel’s two Laws of Heredity
