Answer:
The best answers for this question: Why might a laboratory worker attempting to diagnose a genetic disorder prefer to work with photographs of chromosomes rather than the chromosomes themselves, would be: first, the photograph will capture particularities in a chromosome that the naked human eye cannot detect, and second, it allows for explorations that, if done directly on the live chromosome, would affect it without the possibility of undoing what has been done.
Step-by-step explanation:
Chromosomes, especially when viewed on a device, are pretty fuzzy and difficult to study because of the way they are seen by the naked eye. Also, they are pretty fragile, and when studied, damages can be done that cannot be undone later on. When studying chromosomes, and their particularities, some scientists prefer to use photographic resources for two reasons: the first, a picture may capture certain things in a chromosome that would not be easily captured by the human eye. Also, the time that a photograph can be studied far excedes that which can be used on a live specimen, thus, less damage befalls when using a photograph. Finally, when scientists wish to experiment, and view certain particularities of a chromosome, they will need to manipulate certain things, which, if done on a live chromosome, might damage it. In a photograph, and in a computer program, this damage is non-existent and thus much more studying can be done.
