Genetics I Can Statements (Goals/Objectives )

“I CAN” STATEMENTS for Genetics Unit

Following are the concepts and skills students should have mastered by the end of the unit. [Note for later: Unstarred items are required for all projects.  The test will cover both starred and unstarred items. ]

Mendelian Genetics and Basics

  • I can state basic facts about Gregor Mendel, his work, and his ratios.
  • I can distinguish between probability, possibility, and impossibility.
  • *I can distinguish between the Law of Segregation and the Law of Independent Assortment.
  • *I can link Mendel’s laws to events in meiosis.

 Punnett Squares 

  • I can construct a Punnett square if given genotypes.
  • I can construct a Punnett square if given word descriptions.
  • I can calculate genotypic probabilities from a Punnett square.
  • I can calculate phenotypic probabilities from a Punnett square.
  • *I can construct and interpret a dihybrid cross.

 Vocabulary (heterozygous, homozygous, dominant, recessive, allele, genotype, phenotype, hybrid, carrier, purebred, etc...)    

  • I can consistently and correctly use the vocabulary.
  • I can recognize synonyms in the vocabulary without any trouble.
  • I can associate the vocabulary with appropriate examples.

 Pedigree

  • I can construct a pedigree when given a paragraph description.
  • I can determine the relationship between individuals in a pedigree.
  • I can determine the phenotypes of individuals in a pedigree.
  • I can correctly determine the genotypes of individuals in a pedigree.

 Logic and Comprehension

  • I can support an argument using all of the above.

 Forms of Inheritance (All students should know complete dominance and recognize the existence/key features of other types.  Working with more detail, such as labeling and using Punnett squares, is a starred skill.)

  • I can recognize and explain COMPLETE DOMINANCE.
  • I can compare and contrast complete dominance and incomplete dominance.
  • I can compare and contrast complete dominance and co-dominance.
  • I can give an example of a trait with multiple alleles.
  • I can give an example of a polygenic trait and explain why they have so much variation in phenotype.
  • I can explain why sex-linked traits have different frequencies in men and women.
  • (*)I can describe or give examples of the symbols used to express all of the following
    • complete dominance
    • incomplete dominance
    • codominance
    • multiple alleles
    • sex-linked traits
  • (*) I can construct and interpret an appropriate Punnett square for all of the following
    • complete dominance
    • incomplete dominance
    • codominance
    • trait with multiple alleles
    • multiple alleles
    • sex-linked traits
