What is binary fission? A form of sexual reproduction used by some unicellular organisms to produce two cells that are genetically different from each other and from the parent cell.

A form of asexual reproduction used by some multicellular organisms to produce two cells that are genetically identical to each other and to the parent cell.

The 3rd answer

Explanation:

Binary Fission is the process of cell division in prokaryotes (bacteria). It is a type of asexual reproduction. If the parent cell has 18 chromosomes than each daughter cell will also has 18 chromosomes.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
