Isn't this just a case where the male and female gametes are sufficiently
compatible that a fruit forms (not much of a feat -- plenty of plants
produce sterile/seedless without ever being fertilized), but the male and
female gametes are not sufficiently compatible to fertilize hence no seed
forms?
So, not a genetic change (hybridization) anywhere in the fruit, just a
fruit with null/blank seeds and whatever physiological changes that happens
to induce (e.g. fruit might be smaller, or different shape, etc.).
