The answer to your question begins with the chromosome. A chromosome is an organized structure of DNA and protein that is found in cells. We have about triple the number of chromosomes as human beings than the (simpler) platypus. Fruit development normally begins when one or more egg cells in the ovular (‘egg like’) compartment of the flower are fertilized by sperm nuclei from pollen. In some plants, however, fruit develops without fertilization, a phenomenon known as parthenocarpy. Parthenocarpic fruit has advantages over seeded fruit: longer shelf life and greater consumer appeal.Watermelons and bananas are probably the two most famous examples of seedless technology that exploit this phenomenon.One way to make seedless watermelons is to produce triploid seed (three copies of chromosomes instead of the usual two). As in the case of seedless bananas, triploid watermelons cannot produce functional seed, but they still develop good fruit through parthenocarpy. Plant breeders produce triploid seed by crossing a normal dparent with a tetraploid parent (a parent that has four sets of chromosomes).And, of course, horticulturalists are working actively on using genetic engineering to make plants seedless. I’ll leave it to the experts in that field to seed us with the relevant info on that…….Have a nice week guys!
Mmm, but those banana seeds in seedless bananas are not fertile / viable, Eric.Banana plants are all clones of each other, produced, I think, from root sprouts. Consequently they are all genetically identical and vulnerable to the same pests, especially fungi; Panama disease is one such example, which did for the Gros Michel banana; the Cavendish is similarly threatened by another fungal pathogen although I cannot recall the name of this one.
I don't see the problem. What is wrong?
