When a child has been diagnosed with Tay Sachs Disease they stare into space and don't do anything anymore. They still can walk and act like a normal kid they just don't have the motivation to do so.

The Big B represents that the person does not have Tay Sachs.
The small b represents that the person does have it.
The Bb means that the person is a carrier.
In this diagram:
25% is normal
50% is a carrier

The chart on the left shows that one parent is a carrier. Which means none of their children could get it but they become carries too.
The chart on the right shows that both the parents are carriers so some of their kids are carriers now but one will end up with Tay Sachs Disease.
