this twin is a product of scientific cloning. If scientists have their way,

This first step to better understanding cloning is to hear precisely what
Cloning can be defined as an organism or group of organisms derived from
organism by an asexual reproductive process. Usually members of a clone are
in genes (Clarke, 1). Even though the definition is relatively simple, it
will be several
years before these projects will be technically feasible. Many species are
considered for cloning, but legal battles often halt the complex process
Knowledge of the definition of cloning helps one better understand its
The process of cloning is long and tedious and most uncommonly
After many years of failure to clone using adult animals, most scientists
started to think it
was too tough. However Ian Wilmut of the Roslin Institute in Scotland found

is due to
recent advances of Genetic Engineering. Scientists can now isolate an

nucleus, and inject them into a fertilized egg whose own nucleus has been

famous sheep, is starting to be used more often. This new process involved

attempts, only one

With odds like one out of 300 (the Dolly experiment) successful clones,
examples of cloning are a rarity. However when a successful clone occurs it
is quite a
notable feat. One cloning project currently under way is a revival of the
