Where did seedless watermelons come from?

Seedless watermelon is obtained by artificially inducing polyploidy, such as treating seeds or seedlings of diploid watermelon with colchicine (a plant base) to hinder the formation of spindle filaments and primary walls in the middle of cell division. so that the replicated genome can not be divided to the poles and form a secondary wall in the middle, resulting in the formation of double genome cells and tetraploid watermelon plants. Then the triploid seeds were obtained by crossing with the diploid watermelon plant (as the male parent). The triploid plant could not form normal germ cells because of the disordered synapsis of homologous chromosomes in the process of reduction. Then the mature pollen of diploid watermelon was used to stimulate the flower ovary of triploid plant to form triploid fruit, because its ovule could not develop into seed.

Is seedless watermelon harmful to people?

Seedless watermelons do no harm to people. Seedless watermelon is not genetically modified, the so-called genetically modified food is the use of biotechnology to transfer the genes of some organisms to other species, to transform the genetic material of organisms, so as to optimize and improve their traits, nutritional quality, consumption quality and so on. Seedless watermelon, like ordinary watermelon, is also the product of genetic recombination under the law of nature, and there is no human intervention to change its genes, so eating nature is not harmful to health. Of course, if you eat more, like other watermelons, it will also hurt the spleen and stomach, which can easily cause diarrhea.
