Genetics - Similarly Genetically Different
How can humans who are remarkably so similar be so dissimilar? The answer lies in the fact that although we contain the same chromosomes, the genes on those chromosomes are different.

X or Y--Does It Make a Difference?
Students will describe functional differences of X and Y chromosomes and will explain the significance of differences in X and Y chromosomes in the human genome.

Design a Chromosome
Students will understand the link between genes and chromosomes and reinforce the concepts of dominant and recessive genes, incompletely dominant genes and co-dominant genes.

Creating Chromosomes
This visual exercise helps students understand the concepts of homologous chromosomes, non-homologous chromosomes, crossing over, and deletion.

DNA Concentric Circles
Challenge students to demonstrate their understanding of the difference between genes, chromosomes, and the genome with this simple assessment.

Encyclopedia Analogy
Clearly distinguish between genes, chromosomes, and genomes by using the following analogy: A set of encyclopedias is like all the chromosomes in your cells.

Karyotyping Activity
This exercise is a simulation of human karyotyping using digital images of chromosomes from actual human genetic studies. You will be arranging chromosomes into a completed karyotype, and interpreting your findings just as if you were working in a genetic analysis program at a hospital or clinic.
