Itried to use online to find the answer for this question, but i couldn't find answer for this question: similar genera are grouped into which of the seven major taxons of the taxonomic levels?

There are eight distinct taxonomic categories. These are: Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species. With each step down in classification, organisms are split into more and more specific groups.

"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."

i think its white blood cells

i hope this
