How closely related are the genes on a single chromosome?
For example, are all the genes related to vision on a single chromosome? People are always focusing on individual genes, but the chromosome is the unit of inheritance. Might it be that some of an organism’s characteristics are determined by a combination of genes? If these genes are all on a single pair of chromosomes, wouldn’t it make sense in genetic engineering to swap an entire chromosome?
