The process in which a single plant produces many offspring genetically identical to itself is called cloning.

Here's why:

* Cloning is the process of creating a genetically identical copy of an organism. This can be done through various methods, including taking cuttings from a plant, using tissue culture, or grafting.

* Sexual reproduction involves the combination of genetic material from two parents, resulting in offspring with a mix of genes.

So, since the offspring produced are genetically identical to the parent plant, it's considered cloning.
