Lecture Test 3 Study Guide
The lecture test will be composed of multiple choice questions, and a short
answer section (which consists mostly of genetic cross problems). You should
begin studying for the test well before the night prior to the examination. Below
you will find a series of terms which are found in the text that are important to
your understanding of the material. You should be very familiar with all the
lecture material presented concerning each entry below; the entries under each
