Do all members of a species have the same number of unique genes? I know that each gene is responsible for one or many traits in a species. Is it possible for one member to have a wholly unique gene that is not found in other members or does that imply that the member actually belongs to a different species.
Lets say member 1 in a species has the following UNIQUE genes: A,B,C,D
Is it possible for member 2 to have the following UNIQUE genes: A,B,C,D,E.
I have been told that all members of a species have the same total number of UNIQUE genes. For the case above, either 4 genes or 5 genes. I do not know if this is true.
When i say unique, i am not taling about alleles or damaged genes. I mean a gene that is totally not found in the chromosome of the other member. Would this imply that member 2 has a wholly new trait that is not found in member 1 and therefore, member 2 actually is of a different species from member 1?
Thanks
