Why are some fruits true to seed but others are not?

I understand that you can cut off a branch of s tree and stick it to another tree to get fruit of the original one. But then why don’t you get that exact fruit if you plant seeds of it? But then, there’s other plants where you get the exact same fruit that you ate if you plant it.

Some plants will self pollinate (the pollen from that plant will fertilise it’s own flowers to make a seed) and others need to cross pollinate (use pollen from another plant of the same species, though it may be a different variety). For instance, apples cross pollinate, but there are many different varieties of apple, so chances are the seeds will grow into a different kind of tree to the tree the apples grew on. If a plant will self pollinate, the seeds will be the same variety as the parent plant.
