A 14-nation consortium of geneticists and bioinformatics specialists deciphers the sequence and location of the 35,000 genes of the tomato, an international food crop. This video focuses on the work done by American researchers, who explain the process of genome sequencing, and how a sequenced genome aids plant breeders in selecting precisely for desirable traits, including yield, shape, natural resistance to disease and flavor.

This graphic from Biology by Kenneth R. Miller and Joseph Levine suggests how some recent hominid fossil finds might fit into the overall picture of hominid evolution. As more fossils are found and further analysis advances our understanding of human evolution, this picture will almost certainly be revised.

In this activity students examine karyotypes from five individuals to try to identify which chromosomes determine gender in humans. This activity is also a good illustration of meiotic non-disjunction.

In a class discussion format, the teacher presents background information about basic human genetics. The number of chromosomes in both body cells and egg and sperm cells is covered, as well as the concept of dominant and recessive alleles. Students determine whether or not they possess the dominant allele for the tongue-rolling gene as an example.

Students use DNA profiling to determine who robbed a bank. After they learn how the FBI's Combined DNA Index System (CODIS) is used to match crime scene DNA with tissue sample DNA, students use CODIS principles and sample DNA fragments to determine which of three suspects matches evidence obtain at a crime location. They communicate their results as if they were biomedical engineers reporting to a police crime scene investigation.

Writing a Wikipedia article about a genetic disease is a good culminating activity for a genetics course or module, as it requires synthesizing and interpreting a wide range of genetic information. This assignment also includes a potential service component, which is normally very difficult in genetics.
