Heredity: Crash Course Biology #9

Hank and his brother John discuss heredity via the gross example of relative ear wax moistness. Crash Course Biology is now available on DVD! http://dftba.com/product …

Besides the wet/dry earwax gene, give an example of a human Mendelian trait (determined only by one gene).  For your example, describe the dominant and recessive alleles, and describe the phenotype of an individual that is heterozygous for the gene (1/2 page, 2 pts.).  Cite your source (peer reviewed journal article, .gov or .edu website, or textbook acceptable, 1 pt.).  Next describe one human disease that is caused by a mutation on an autosome.  Discuss the genetics of the disease (dominant or recessive) and the symptoms of the disorder (3/4 page, 3 pts.).  Cite your source (peer reviewed journal article, .gov or .edu website, or textbook acceptable, 0.5 pt.).  Finally, describe one human disease that is caused by a mutation on a sex chromosome.  Discuss the genetics of the disease (dominant or recessive) and the symptoms of the disorder (3/4 page, 3 pts.).  Cite your source (peer reviewed journal article, .gov or .edu website, or textbook acceptable, 0.5 pt.).  Total length of 2 pages, 10 points total.

This report will be due next Wednesday.
