genetical relationship of apple and peach
 

Are apple and peach genetically related (and how)?

As I am not a biologist, I tried to simply google this.
People say apple, peach and quince are closely related,
they show this result by similarity tables, but no web
site I found made any statements on the genetical affinity
of apple and peach.

Thanks in advance,

Claudio
