Enduring Understandings
•
The work of Gregor Mendel describes the basis by which traits, coded for by genetic
information, are passed from one generation to the next.
Essential Questions
•
How is heritable information passed from one generation to the next?
•
What are different patterns by which heritable information passed from one generation to
the next?
•
How does this unit provide evidence of the relatedness of living things in the world?

Learning Targets
1. Be able to discuss the genotypes and phenotypes of Mendel's P, F1 and F2 generations
and be able to carry out these crosses.
2. Know Mendel's Law of Segregation and Law of Independent Assortment and illustrate
these laws in an appropriate cross.
3. Be able to carry out crosses concerning complete dominance, incomplete dominance,
codominance, sex-linked inheritance, multiple alleles, and dihybrid crosses in addition to
understanding polygenic inheritance.
4. Be able to interpret pedigrees.
5. Be able to identify and distinguish between the following autosomal genetic diseases:
sickle cell anemia, cystic fibrosis, hemophilia, huntington’s disease
