The effect is called "genetic linkage" and is caused by pairs of genes being close enough to each other that there is a reduced chance of them being independently inherited. The closer they are, the less likely they are to separate. The further away they are, the more likely they are to separate, up until they show no linkage at all.
Even two halves of the same gene will occasionally be swapped between chromosome pairs and thus get inherited independently. It's all about numbers and statistics.
