You are welcome.

I should add that I have assumed that fruit trees have hermaphrodite
flowers with both male and female parts. All the fruit tree in my garden
fit in to this category.

If a plant is monoecious (seperate male and female flowers on the same
plant) or dioecious (seperate male and female plants) then only the
female flowers are potential fruits.
