I'm sorry if "gene markers" is not the correct word. An edit could be appreciated but I don't study in an English speaking country unfortunately.
In a family, there is a genetic, dominant disease. The father and a son is sick. A gene marker analysis is performed with markers close to the assumed mutated gene on chromosome 11.
How do I read these and "What sort of markers are these"? I'm not sure what is going on here and I'm not sure what to search either due to language problems.
