Genetic similarity is high between a peach and an almond and you can cross them.

There is a theory saying peaches and almonds have a common ancestor originating in Asia and these species separately evolved after lifting of Himalayas. [1]

Peaches originated in northwest China. Wild almonds originated in central and western Asia. Today peaches are native to northwest China and almonds are native to Iran.
