First question here so sorry if it is about both genetics and evolution.
So, if I get a disease which can be clearly identified on the gene level and all my descendants inherit it, after 500 years do all people with the disease share the common ancestor (given that it's only inheritable)?
I mean, my clear guess first would be "yes" but I really want to check it since I haven't read it anywhere.
Feel free to post materials on this too. Thanks!
