Linkage occurs when two different genes are located on the same chromosomes
- For this reason they are usually inherited together and end up in the same gamete
- Under normal circumstances, the linked genes on the same chromosome pass into the gamete and then into the offspring together
This is contrarty to Mendel's law of independent assortment.
If genes A & B had been on separate chromosomes, then there would have been more genetic variation in the gametes and in the offspring.
Independent assortment would have allowed parents AaBb to produce two types of games
