Surprising New Twists in the Study of Inheritance
Tamsen K. Meyer and Cheryl H. Powers
1994 Woodrow Wilson Collection
Just when you thought you had Mendelian inheritance and molecular genetics "wired"...
These are intriguing questions you and your students may be asked. Recent revisions to the basic mechanisms of modern genetics violate many long held ideas of inheritance. You may wish to have students investigate how an understanding of mitochondrial DNA, jumping genes, junk DNA, introns, genomic imprinting, anticipation, the "not-so-universal" genetic code, and directed mutations help answer these questions. The teacher may wish to develop a study guide that would accompany reference articles on these anomalies. Background information is summarized for the teacher, since older textbooks will not have references for these genetic surprises.
