What do you get when you download VGL?
VGL shows color images of the phenotypes and only presents problems with one gene.
You get the following files & directories:
- VGL
- The VGL program. Use this to run simulated genetics problems.
- Problems
- This directory contains several sample problems. The levels correspond (approximately)
to the level of difficulty. The types of problems available at each level are shown
in the table below; VGL randomly selects from the possible models at each level
at the start of every new problem. For more details on the genetic models
and practice mode, see the User's Guide.
- Level 1: 2-alleles only;
autosomal inheritance only;
simple dominance only;
practice mode.
- Level 2: 2-alleles only;
autosomal inheritance only;
simple dominance only.
- Level 3: 2-alleles only;
autosomal or XX/XY sex-linked inheritance;
simple dominance only;
practice mode.
- Level 4: 2-alleles only;
autosomal or XX/XY sex-linked inheritance;
simple dominance only.
- Level 5: 2-alleles only;
autosomal, XX/XY or ZZ/ZW sex-linked inheritance;
simple- or incomplete- dominance;
practice mode.
- Level 6: 2-alleles only;
autosomal, XX/XY or ZZ/ZW sex-linked inheritance;
simple- or incomplete- dominance.
- Level 7: 2- or 3- alleles;
autosomal inheritance only;
simple-, incomplete-, circular-, or
hierarchical- dominance; practice mode.
- Level 8: 2- or 3- alleles;
autosomal inheritance only;
simple-, incomplete-, circular-, or
hierarchical- dominance.
- Level 9: 2- or 3- alleles;
autosomal, XX/XY or ZZ/ZW sex-linked inheritance;
simple-, incomplete-, circular-, or
hierarchical- dominance; practice mode.
- Level 10: 2- or 3- alleles;
autosomal, XX/XY or ZZ/ZW sex-linked inheritance;
simple-, incomplete-, circular-, or
hierarchical- dominance.
What do you get when you download VGLII?
VGL shows the phenotypes as simple color images and presents problems with one to three genes.
You get the following files & directories:
- VGLII
- The VGLII program. Use this to run simulated genetics problems.
- Problems
- This directory contains several sample problems. The levels correspond (approximately)
to the level of difficulty. The types of problems available at each level are shown
in the table below; VGL randomly selects from the possible models at each level
at the start of every new problem. For more details on the genetic models
and practice mode, see the User's Guide.

Files with names like Level01p.pr2 create the same level of problems as Level01.pr2, but allow
practice mode.
Problem files can be custom-written for specific needs. Please contact the author
(Brian White) if you would like
a custom problem file or to learn how to make your own.

Frequently Asked Questions
- When I double-click a Problem file or my saved work, VGL (or VGLII) does not start. What
is wrong? VGL and VGLII do not launch automatically when you click on these files.
You must launch VGL(II) first and then open the files from within VGL(II).
- VGL opens properly but, when a new problem is selected and opened, nothing happens. What
is wrong? You have an older version of Java installed. You should download the latest
version of java
(it is free).
- Can I exchance files between VGL and VGLII? No. The files are incompatable.
