Transmission genetics simulation. The Virtual Genetics Lab (VGL) is a simulation of transmission genetics that approximates, as closely as possible, the hypothesis-testing environment of genetics research. In this lab, students cross hypothetical creatures and examine the progeny in order to determine the mechanism of inheritance of a particular trait. As in actual research, it is not possible to 'see the answer' - the student must decide for herself when she has collected enough data to be sure of her model. The goal is to have students understand the logic of genetic analysis - how one can use crosses to determine how a trait is inherited and reinforce their understanding of transmission genetics.

The Goals and Objectives of the Lab
When you start the problem you are given a cage of a population of creatures collected in the field. Each of these creatures will display one of two or three different traits of one particular character (for example, if the character is Body Color, the traits might be Red Body and Green Body). Your task is to discover how this character is inherited. You determine this by crossing particular individuals and observing their offspring. You then use the resulting data to deduce the underlying genetic model that determines the inheritance of this character. You must decide when you have collected enough information to be convinced that you are right - the program will not tell you the right answer.

When you start a new problem, VGL randomly chooses a character from a list of possible characters. It then randomly chooses a genetic model from a list of twelve possible genetic models. The range of possible models is be custom-configured by your instructor when she creates a problem type; different problem types can have greater or fewer possible models and Practice Mode can be enabled or disabled for a particular problem type. Since this assignment is random, the same character can be inherited in different ways in different problems.
