Reply to comment by dion_o in When it's said 99.9% of human DNA is the same in all humans, is this referring to only coding DNA or both coding and non-coding DNA combined? by PeanutSalsa

We have almost no homology with lettuce. 10-15 % of coding DNA maybe . If you cherry pick (lettuce pick ?) certain genes common to all life on earth , then unsurprisingly we have 99% similar genes. But what about the lettuce genes for the spine? Or blood cells? There’s no way to compare because plants lack these genes completely.

And comparing to chimps even is misleading. Which genes are you comparing? Do they have to be 100% the same to count as 100% homologous? Any two cells in my body might be off .1% which changes count? One paper I read said we are only 18% homologous to chimps
