The ability for mammals to tolerate aneuploidies in the sex chromosomes arises from the ability to inactivate themwhich is required in normal females to compensate for having two copies of the chromosome.

|After aging the slides in an oven or waiting a few days they are ready for banding and analysis. On the other hand, males are haploid, since they have a single version of these genes.
This method is particularly helpful for staining the distal ends of chromosomes. Strains of the bacterium Enterobacter, similar to newly found opportunistic infectious organisms seen in a few hospital settings, have been identified on the International Space Station ISS. Stocks containing inversions at a known initial frequency can be maintained in controlled conditions. The slides are then dehydrated in ethanoland the probe mixture is added.
