      Hi,

      Please do note that I am quite ignorant regarding human biology. Having
      said that, lets begin.

      Is it possible for 2 individuals within the same species to have
      different number of genes?

      If it is, then lets say individual A has 50 genes and individual 2 has
      51 genes. Is it possible for them to interbreed?

      If it is, what happens to the extra gene since I believe that genes
      only exist in pairs.

      Thanks

      it is impossible for individuals of the same species to have different no. of genes. like the species of humans hv 23 pairs of homologous chromosomes with equal no of genes on them for every individual in the human race.

      Normally, one species has same number of chromosomes, further same number of genes or DNA. If there is an extra stuff, we call it as mutation. Mostly, individuals with mutation (mutant) is sterile to anticipate the change of genetics of the species.
