Magento

Hey guys,

Is there a way to get the parent product for the related product.
For example I have two products Product1 and Product2.
On Product1 edit page I set the option that Product2 is related for Product1.
Is there a way to determine from Product2 that it is a related product for Product1.
Please notice that I am not talking about configurable and simple products. Both products Product1 and Product2 are simple.

Regards
