cloning

The other use of the word cloning means to make a copy of an entire organism
as a reproductive strategy. When referring to a whole creature as opposed to
DNA, a clone is an organism that’s created via asexual reproduction, meaning
offspring are produced without the parent having sex first. Cloning occurs naturally
all the time in bacteria, plants, insects, fish, and lizards. For example,
one type of asexual reproduction is parthenogenesis, which occurs when a
female makes eggs that develop into offspring without being fertilized by a
male (for some of you female readers, I’m sure this sounds very appealing). So
if reproduction by cloning is a natural, normal biological process, what’s the
big deal with cloning organisms using technology?
