Question

The scientist who performed successful animal cloning for the first time is
A. Flemming
B. Jenner
C. Watson
D. Ian Wilmut

Answer 1

Hint: Cloning is a method employed for producing individuals that are identical genetically through natural or artificial means. In general terms, one can refer to biological copying as cloning. The term clone was coined by an American plant physiologist named Herbert John Webber. Cloning is a general phenomenon in nature where organisms reproduce by asexual means which is quite predominant in plants.

Complete answer: Cloning in animals becomes of importance in order to procreate desirable genomes and to preserve valuable or endangered genetics. The animal species that have been successfully cloned are sheep, goat, cow, swine, horse. mules, rabbits, rats, mice, cats, and one dog. Clones are the same as identical twins the only difference being that they are born at different times.
Clone is also not some form of mutant and not even some weaker or less potent version of the original type.
The first successful animal cloning:
The first successful animal cloning was conducted on the fifth of July 1996 on a sheep which was named Dolly. She was the first mammal to be cloned by human beings. This phenomenon of cloning was conducted by two researchers named Ian Wilmut and Keith Campbell at the Roslin Institute of University of Edinburgh, Scotland. For creating the clone cells were taken from a six-year-old ewe and were cultured in the lab, once normal eggs have produced the eggs were implanted in surrogate ewes and 148 days later one of the surrogate mothers gave birth to Dolly.
Hence, the correct answer is option (D)-Lan Wilmut.

Note: Lan Wilmut was an english biologist and embryologist. Dolly’s was initially entitled “6LL3” which was later named after singer and actor Dolly Parton. Dolly was also mated to a male sheep called David after which she gave birth to four lambs. After her demise on 14 February 2003, her body was stuffed and has been kept on display at the National Museum of Scotland, Edinburgh.
