Students complete a pre-test on the relationship between heredity and the environment. As a class, they write down descriptions of themselves and identify which ones can be changed and not changed. In groups, they determine which genes are dominant and recessive and develop a model of DNA. To end the lesson, they research a genetic disorder and write a geneotype for each member of the class.

Students comprehend that karyotyping is a process in which chromosomes are cut from an enlarged picture and arranged in decreasing order of size. The cells to be viewed are first chemically treated to increase the number of dividing white blood cells and then treated with colchicines to stop mitotic division during anaphase. Lastly, the cells are burst open, stained and fixed. The slide is examined for well spread chromosomes, photographed, and karyotyped. Full Review »
