First of all, let me be clear about the difference between a hybrid vs GMO food since most of you ( including myself ) avoid buying seedless food in grocery stores not knowing the facts and the entire process of cultivating seedless food.
Hybrid & Seedless Fruit
Hybrid fruits are simply the product of cross-breeding two similarly related species, a process that dates back to the early days of agriculture. Hybridization also occurs naturally in both animals and plants without human intervention.
In the case of hybrid fruits, farmers simply breed two parent fruit trees through cross-pollination to create a hybrid fruit tree that produces fruits that have the most desired characteristics of its parents.
Examples of common hybrid fruits include the pluot (plum and apricot), tangelo (tangerine and pomelo) and grapefruit (pomelo and orange). In fact, the vast majority of products that you consume exists due to hybridization and breeding. In the case of watermelon, when a hybrid watermelon is pollinated with a regular watermelon, it creates a sterile offspring (i.e seedless watermelon = hybrid watermelon + regular watermelon). For watermelons, being sterile means the seeds are white, small, and edible, which is the desired characteristic for seedless watermelon.
Regular watermelons are diploid organisms and have 22 chromosomes. A hybrid watermelon is basically a watermelon with 44 chromosomes (tetraploid). When a tetraploid watermelon is pollinated by a diploid (regular) watermelon, the offspring is a triploid watermelon with 33 chromosomes. A triploid watermelon is a seedless watermelon. Without a detailed description of the process of getting triploid watermelon, I will jump to the point. Based on the research done, it is clear that the triploid organism IS NOT GENETICALLY ENGINEERED by adding, deleting or replacing watermelon genes with genes from other organisms. Instead, it is just inhibited from completing a natural cycle in reproduction called ANAPHASE. More information on breeding of seedless watermelon can be found here: http://cucurbitbreeding.com/watermelon-breeding/seedless-watermelon-breeding/
Most modern fruits and vegetables – including kale, carrots, broccoli, apples, bananas – you name it – are essentially hybrids that are nothing like their ancient, wild counterparts.
MOST OF US WOULD LIKE TO KNOW IF THER ARE ANY RISKS AND SIDE EFFECTS CONSUMING HYBRID FRUITS?
There are no known risks associated with consuming edible hybrid fruits. Many of these fruits have existed for decades, or even much longer.
Note that almost all modern fruits and vegetables that we eat today are the products of hybridization.
Genetically-Modified Organisms (GMOs)
Genetically modified organisms (GMOs), in contrast, are the result of combining DNA molecules from different sources in order to alter the genes of an organism through bio-engineering. GM is a laboratory-based technique that is completely different from natural breeding.
Usually, DNA for a genetically modified organism does not come from closely related species. Bio-engineering is a strictly human-driven process and cannot occur naturally, or without human intervention.
Are There Any Risks To Consuming GMOs?
I will not go into depth in regards to this controversial theory, but rather outline some major facts.
Bio-engineering plants or animals that are used for food have the potential to produce toxic byproducts. For example, a food crop might be bio-engineered to be resistant to herbicides, thus allowing the farmer to spray liberal amounts of herbicides to control weeds without impacting the food crop. This could increase the amount of herbicide or pesticide that finds its way into the food.
Making a food crop that is bio-engineered to resist pests, could have possible side effects by making the crop toxic, allergenic or reduced in nutritional value. Besides the listed above, this process can cause the crop to be damaging to the environment and reduce the GM crop’s productivity. Concluding that this might have a large impact on humans.
Seedless watermelons, grapes, bananas, and oranges are not GMOs. Rather, seedless fruits are created from plants that are either not fertilized by pollination, or that have been pollinated but do not develop mature seeds.
Fruit cultivars may create seedless fruit by cross-breeding normal fruit trees with fruit trees that contain extra chromosomes, which result in infertile offspring producing seedless fruits.
