Tay-Sachs disease is a rare inherited disorder that progressively destroys nerve cells in the brain and spinal cord. It is controlled by a recessive allele of gene. Individuals with the disease die at a young age and can’t reach adult hold to marry and bear children.

She told you that her grandmother’s older brother died of the same disease at a very young age and her fathers family also has history of the disease.

Use punnet square to explain to your best friend how Tay Sachs disease is inherited.
