Ramets are the group of genetically similar individuals that are produced asexually from the same organism. Each individual of ramet are clones of each other. They are genetically identical individuals that are originated from a common ancestor. The youngest ramets are photosynthetic, and they provide carbohydrates which support the forward growth of rhizomes and new ramets, and sustain the root systems of several generations of older ramets.

A clone is a group of individual that are genetically identical. Clones are produced by asexual reproduction or by inserting a nucleus from a mother cell to the donor egg cells. Dolly was the first animal to be cloned.

Organisms comprise genetic material organised in the form of DNA or RNA. Genes are the fragments of DNA that are heritable through generations. Gene pool is the totality of all the genes present in the interbreeding population. Heritable mutation increase the gene pool and deletion of a gene from the species leads to a decrease in the gene pool.
