A genetic test for haemochromatosis – Online course

Explore how hereditary hemochromatosis affects the body. Examine the most common mutation of the HFE gene that introduced an allele coding for a defective HFE protein. Use modelling to investigate how the alleles inherited by an individual can be detected using a restriction digest and gel electrophoresis. Analyse a DNA profile to determine the allele status of individuals in a family and construct a pedigree chart to represents the allele status and disease status of individuals. Use a pedigree chart and punnet squares to predict the outcomes of genetic crosses.

This course also involves the use of a printable model to explore HFE gene alleles. Click here to download and then print the model.
