Understand…

The work of Gregor Mendel and his contributions to our current understanding of genetics.

Mendels Law of Dominance , Mendel’s Law of Segregation and Mendel’s Law of Independent Assortment.

How traits are passed from parent to offspring.

The definition and function of genes.

How to determine genotypes from given phenotypes.

How to determine phenotypes from given genotypes.

The difference between the complex inheritance patterns – incomplete dominance, codominance, etc.

The types of genetic disorders discussed in class and their causes/symptoms.

Why more males are colorbind than females.

How the major forms of biotechnology are used by today’s scientists.

Be Able To…

Complete a monohybrid punnett square for any inheritance pattern.

Analyze punnett squares in order to determine offspring probabilities.

Complete and analyze a dihybrid cross.

Describe the basic causes and characteristics of the genetic disorders discussed in class.

Identify family relationships by observing a pedigree.

Determine genotypes of individuals by analyzing how traits are passed through a pedigree.

Identify the gender and chromosomal condition of a person by analyzing a karyotype.

Defend this statement: males cannot be carriers of hemophilia (a sex-linked trait).

From previous unit: know the overall purpose of replication, transcription, translation, protein synthesis.
