Chromosome “theory” of inheritance
... This issue has been studied experimentally, and it was found that in a given species, the distribution of genes between chromosomes, and – within each chromosome – their order are both invariant. In other words, if we examine chr. 1 (by the way, they are numbered according to size, eXcept for the X) ...
