CRISPR, which is essentially a genetic copy-and-paste tool — makes modifying the cells at certain spots easier.

While studying the reproductive habits of the Squalius alburnoides, researchers found a single fish (out of 261) that is a perfect genetic copy of its father.

But this is the first time that scientists are using cells edited with CRISPR — a genetic copy-and-paste tool that makes modifying cells easier and cheaper.

The idea was that Mark would serve as a control subject — a nearly identical genetic copy that NASA could use to figure out how the space environment changed Scott's body.

As well as cloning thousands of farm animals ViaGen, a small firm based in Cedar Park, Texas, has cloned many horses and pets; there are people happy to spend lavishly in the hope that they can get a genetic copy of a lost companion.

This species is also capable of asexual reproduction through longitudinal fission. In essence, an anemone will split into two pieces, and each will become a genetic copy of the other. Burrowing anemones are carnivores, eating unwary crabs that wander into their stinging tentacles. They are in turn preyed upon by the nudibranch Aeolidia papillosa, and likely other nudibranchs and small fish as well.

The Doctor arrived in time to stop her. In this story, a genetic copy of Roz was also created from her ID implant, which the real Roz eventually killed. Roz and Chris meet the Fifth Doctor and his companions in the novel Cold Fusion. Roz and Chris travelled with the Doctor for many adventures and while their relationship was strictly platonic, she did kiss him in The Death of Art.

The Heck horse is a horse breed that is claimed to resemble the tarpan (Equus ferus ferus), an extinct wild equine. The breed was created by the German zoologist brothers Heinz Heck and Lutz Heck in an attempt to breed back the tarpan. Although unsuccessful at creating a genetic copy of the extinct species, they developed a breed with grullo coloration and primitive markings. After the Nazi invasion of Poland, they were introduced to the Białowieża Forest, where a small herd still survives.

Transposable elements are regions of DNA that can be inserted into the genetic code through one of two mechanisms. These mechanisms work similarly to "cut-and-paste" and "copy-and-paste" functionalities in word processing programs. The "cut-and-paste" mechanism works by excising DNA from one place in the genome and inserting itself into another location in the code. The "copy-and-paste" mechanism works by making a genetic copy or copies of a specific region of DNA and inserting these copies elsewhere in the code.

Throughout their time at the academy, astronaut candidates must overcome numerous physical and mental trials. Readers discover from a pre-serialization story that Asumi's mother dies following the Lion disaster, but this is not known to Asumi's friends until Kei discovers the obituary listing in a newspaper article. Marika is revealed to be the genetic copy of a deceased Marika Ukita despite a standing ban on human cloning. Fuchuya suffers from red-green color blindness after his eyes are exposed to an exploding firework at close range in a childhood accident.

The duplication and transmission of genetic material from one generation of cells to the next is the basis for molecular inheritance and the link between the classical and molecular pictures of genes. Organisms inherit the characteristics of their parents because the cells of the offspring contain copies of the genes in their parents' cells. In asexually reproducing organisms, the offspring will be a genetic copy or clone of the parent organism. In sexually reproducing organisms, a specialized form of cell division called meiosis produces cells called gametes or germ cells that are haploid, or contain only one copy of each gene.

In 2002, Lyons made international headlines by analyzing the DNA of the world's first cloned cat, a kitten named Cc:, and confirming that it was indeed a true clone, a genetic copy of its mother. Lyons has helped develop DNA tests for polycystic kidney disease (PKD), an inherited condition that shortens the life of cats by causing them to suffer kidney cysts. Previous tests for this condition involved ultrasound and were not very accurate, unlike the DNA test devised by Lyons. Approximately one third of all Persian cats carried the PKD gene at one time, but because of ultrasound testing and the newer, more accurate DNA tests, these PKD-carrier cats are gradually being identified and removed from the feline gene pool by spaying and neutering.
