In viticulture, this is understood to mean the young vine germinated from a planted grape seed. The germination of a seedling can occur independently in nature or be deliberately induced by humans. In contrast to a genetically identical clone, which results from vegetative propagation as a cutting (seedling), seedlings resulting from generative or sexual propagation are fundamentally different genotypically. Compared to other plant groups (e.g. trees), the grapevine is extremely heterozygous and cannot be propagated by seed (grape seeds). The berry seeds carry the paternal genes passed on at fertilization. For the appearance and varietal typicity of the grapes, however, it is completely irrelevant by which paternal variety the fertilization took place. These correspond to 100% of the type of the mother variety, independent of this.
