a rooted cutting from a plant

Answer

If by clone you mean a sport that is visually different from the parent then you can. If by clone you mean a cutting of the parent and the parent is covered by Plant Breeders Rights legislation then it is illegal to sell rooted cuttings of that plant though you can give them away.

they physically cut and remove either the anthers from the receptor plant or the stigma from the pollen donor plant.

In a red rose bush plant breeders may look for good pollen, a good shine in color, and for it to grow well. These are just a few suggestions to help you as this may get you started trying thinking out of the box or if you now any one who is a plant breeder ask them for help.

When purchasing a pedigreed cat, "breeding rights" means that the offspring may be registered with one or more of the registering associations (TICA, CFA, GCCF, FiFE, ...). If you purchase a cat without breeding rights, you can exhibit it in competition, but you cannot register its offspring.

Breeders typically sell cats without breeding rights when they feel that the cat does not represent the breed well enough to be used in a breeding program. The cat may still be a beautiful example of the breed and make a wonderful pet. A pedigreed cat without breeding rights is generally much less expensive than one sold with breeding rights.

Due to the prevalence of "backyard breeders", who don't care about registration or pedigrees, reputable breeders increasingly rely upon early spay/neuter, rather than withholding breeding rights, to prevent unauthorized breeding from their lines.
