Why is the genetic code of an oak tree more similar to a mosquito than to an elm tree?

The genetic code of an oak tree is not more similar to a mosquito than to an elm tree. The genetic code refers to the set of rules whereby living cells translate information on development, functioning, growth and reproduction in deoxyribonucleic cid (DNA) and on controlling synthesis in ribonucleic acid (RNA) into proteins. An oak tree, as a woody plant, will have a genetic code that is more similar to an ash, elm or maple tree, as woody plants, than to a chipmunk, mosquito, octopus or squirrel, as animals.
