I have forwarded it to a friend who has a PhD in biology and who does lots of research involving comparative gene sequencing in various organisms. I expect to hear back from him in 12 to 24 hours and will post again then.
1) There are online databases of genetic sequences of organisms. I am not familiar with them (except for OMIM, which covers human mutations), but anyone can access these databases. Someone who is familiar with such databases will have no problem finding identifying the the two sequences RedCollie1 is comparing and verifying or refuting that that difference in sequences exists.
2) To evaluate whether or not that specific difference in the sequences indicates what RedCollie1 claims it indicates is another matter. That would require considerable expertise.
It is original research, so "Twatter OP" is the source. It is worth our while trying to verify or refute his find, and his interpretation of what he has found.
