What does the phrase ';true to form'; mean as far as pomegranate seeds go?

I keep reading that when you germinate pomegranate seeds they do not come ';true to form'; and i cannot find out what that means. Please Help. Thanks :)What does the phrase ';true to form'; mean as far as pomegranate seeds go?
When they say a fruit does not ';breed true'; from seed, it means that the seed will produce a tree that will produce fruit that may be a slightly different variety.





Apples are the same way. To get another Gala apple tree, you have to graft a piece of a gala apple tree onto fresh root stock, and grow a new tree. If you plant a seed from inside a gala apple, you will get a hybrid...a cross between the mother tree (the gala), and whatever tree pollinated it. It may be a great apple, may be not so good...it's kind of a genetic toss up.





It's also very like the ';seed'; from a human not producing an identical human. It's a genetic cross between the mother and father - not an identical human to the mother who carried the seed.What does the phrase ';true to form'; mean as far as pomegranate seeds go?
True to form simply means that the offspring will be exactly like the mother plant and produce exactly the same fruit. Hybrids plants are genetically altered and usually will not grow true to form, meaning the new plant may or may not resemble the mother plant and may produce inferior fruit or no fruit at all.
It means the fruit came from a Hybrid tree and the seed will not produce a hybred tree.
