Animal cloning is a technique for the
production of genetically
indistinguishable copies of the desired
animal.
●This cloning process is done by technique
called somatic cell nuclear transfer.
●This technique involves transfer of somatic
cell nucleus into an egg cell.
●Artificial Embryo twinning is another
method of cloning in which an
indifferetiated embryo is artificially divided
into two or more embryos.
●These embryos develop into genetically
identical offsprings i.e. Clones.
●Till today, adult animals such as
cattle, pigs, rabbits, sheep, and
goats have been cloned using
nuclear transfer from a somatic cell.
History of Animal Cloning
Dolly, female Finn Dorset sheep that lived
from 1996 to 2003, the first clone of an
adult mammal, produced by British
developmental biologist Ian Wilmut and
colleagues of the Roslin Institute, near
Edinburgh, Scotland
Ian Wilmut with Dolly
●1885 : First Ever Demonstration of
AET in invertebrates
●1902 : AET in Vertebrates
●1975 : First Mammalian Embryo
created by NT in Rabbit.
●1996 : Dolly Sheep created by Ian
Wilmut using SCNT
●2001 : Endangered Animal cloned by
SCNT.
Purpose of Animal Cloning
●Genetic Preservation:
To preserve desirable genetic traits in
animals for continuation of specific and
beneficial traits.
●Reproduction of Elite animals
Production of high performing and Elite
Animals with superior agricultural and
economic traits.
●Livestock Improvement:
Improved livestock production by animal
cloning with desirable characteristics such
as high milk yield or disease resistance
●Biomedical Research :
Cloned Animals are used for biomedical
research to help in studying diseases and
developing treatments.
●Conservation of Endangered
Animals:
To increase population of endangered
species and prevents species extinction.
Ethical Concerns
Animal welfare :
Involves the addressing ethical concerns
and ensuring the well-being of Cloned
Animals.
Lack of Genetic Diversity:
Cloning reduces genetic variability which
makes the clones more susceptible to
diseases.
Disturbance of Natural Order:
Cloning interferes with natural order of life
raises moral objections.
Allocation of Resources:
Cloning may divert resources from other
important areas such as conservation
effects.
Animal Welfare
●High Failure Rates :
Cloning is often leading to high rates of
pregnancy failure and birth defects.
●Health Problems:
Cloned Animals may experience various
health issues including premature aging,
cardiovascular issues and immune system
deficiencies.
●Abnormalities and Deformities:
Cloned Animals may exhibit abnormalities
and deformities of organs.
●Psychological Well-being:
Concern due to factors like potential
isolation,identity issues and stress during
cloning process.
Regulation and Oversight
.
●Balancing Ethical Considerations
with scientific Advancements
●Importance of strict regulations to
ensure responsible use of cloning
technology.
Alternatives and Sustainable Practices
●Exploring alternative methods that
prioritise animal cloning:
Researching alternatives like in vitro meet
can priorities animal welfare over
traditional methods.
●Encouraging sustainable practices
in agriculture and research in
animal cloning
Promoting sustainable practices in animal
cloning involves prioritizing Ethical
treatment, minimising environmental
impact and ensuring the well-being of the
cloned animals.
