🧵 I calculated gene similarity percents

I made up a method to find out how many positions in a gene are identical inbetween human and fish: it is 78% so there is only 22% difference

How?
First human and fish gene need to be pumped into alignment by Mr. Muscle

Then delete the odd 2 or 3 letters from the end since human gene is few characters longer, it doesnt matter in the grand scheme of things, the gene is more than 1500 letters long

Turn letters A,T,C and G into numbers, it can be anything as long its the same for both human and fish. (A=5, T=8, whatever)

Put both 1500 long strings into spreadsheet
Deduct one string from another.
Calculate how many 0:s you got since if its 0 it was identical hit, if its +5 or -5 or whatever it wasnt identical.

So if you get roughly 1200 zeroes in 1540 lengh thats 78%
