• Incomplete Dominance Extending Mendelian GeneticsCodominance Ch 7 Resources     Bio textbook
    Chapter Objectives:

    ·       Identify human genetic disorders caused by inherited recessive alleles

    ·       Determine the inheritance of sex-linked traits.

    ·       Analyze  the inheritance patterns of incomplete dominance and codominance

    ·       Describe polygenic traits and the effect of environmental factors on phenotype.

    ·       Explain how gene linkage maps can be used to estimate distances between genes.

    ·       Identify several methods for mapping human chromosomes.

    Lesson Focus:
