1．What are the advantages and disadvantages of cloning?

Scientists have known for some time that cloned organisms are not always
identical: their observable characteristics and traits can vary, and this variation
can be passed on to the next generation. This is despite the fact that they are
derived (获得) from genetically identical founder cells.

Science and Technology, Saudi Arabia, believe they have found out why this is the
case in plants: the genomes (染色体) of regenerate plants carry relatively high
