Sure they can cross (a relatively low percentage of crossing - 5-8%) but it only affects the seeds not the fruit so no, you aren't growing Ramapo fruit on the 4th of July plant. Since you wouldn't save the seeds from them anyway it is no problem.

Some who have thought that was what was happening in the past later discovered inter-twined branches instead. :-)

Thanks again Dave,

I was thinking that but unsure plus the "4th" seeds were from a generic label so who knows what they are. I will check to see if the branches are intertwined. Very possible since they are right next to each other.
