This animation explains how Nettie Stevens research on meal worms unlocked the chromosomal basis of gender.

Learn about the traits that are linked to genes on the sex chromosomes.

Explains basic genetics concepts, including genes, DNA, chromosomes, sex chromosomes, how traits are inherited, genetic variation, cloning, and stem cells.

Thomas Hunt Morgan will explain the research he did to determine that some traits are linked to the sex of an individual.

A self paced tutorial covering chromosomal testing and the many types of conditions resulting from chromosome abnormalities.

[Free Registration/Login may be required to access all resource tools.] What determines if a baby is a male or female? Recall that you have 23 pairs of chromosomes-and one of those pairs is the sex chromosomes. Everyone has two sex...

Get an in-depth look at gene inheritance and transmission with this webpage. This site explores genetics beyond Mendel and his peas. Investigate transmission genetics with the following topics gene linkage, variation in gene expression,...

Find out about aneuploidy and nondisjunction, as they relate to down syndrome and other related disorders. Also learn about chromosomal rearrangements.

This resource will explore sex-linked genes which are a form of genetic linkage that depends on the X and Y sex chromosomes.

This site from the University of Arizona provides great information on a sex-linked inheritance problem set. This is a very good site to practice what you know about sex-linked problems. Each link is a problem.

This site covers information on all the human chromosomes, has interesting illustrations as well.

This site, provided by The University of Arizona, gives a good set of genetics problems that involve sex-linked genes. Great to review what you know! Links are provided to access the various subjects covered in this problem set.

Brief tutorial dealing with Klinefelter's diagnosis. Provides illustration of nondisjunction and Klinefelter's karyotype. Information provided regarding other sex chromosome aneuploidies.

Here are graphics illustrating an experiment with drosophila fruitflies. Sex-linked inheritance is demonstrated here using eye color alleles on X chromosomes. Site by Access Excellence.

Chromosomes carry genetic information in a molecule called DNA. A type of cell division called mitosis ensures that when a cell divides each new cell produced has the same genetic information. Links to a video and a test are provided.

This interactive learning module allows AP Biology students to explore the principles of Mendelian genetics and non-Mendelian patterns of inheritance. Students will also study the role of chromosomes in heredity.

This Department of Energy site has up-to-date information and statistics on the progress of all JGI genome sequencing projects.

This site from the University of Arizona runs a two-step simulation of Genetic Drift. There are teacher's notes included. A great site to aid in understanding Genetic Drift.

This link has many tools to help understand the revolutionary sciences and discoveries in genetics.

Using chromosome and gene models, students play the roles of two parents in this genetics simulation. The object is to create four offspring and determine their genotypes and phenotypes, and determine the probability of having offspring...
