What type of chromosomal abnormality can lead to multiple copies of a gene, some of which can incur mutations that can lead to t
koban [17]

A trisomy is a chromosomal condition characterized by an additional chromosome. A person with a trisomy has 47 chromosomes instead of 46.

Trisomy means the presence of an extra chromosome in some or all of the body's cells. This results in a total of three copies of that chromosome instead of the normal two copies. For example, Down syndrome (trisomy 21) is caused by having three copies of chromosome 21 instead of the usual two copies.

This genetic condition is the result of a genetic mutation where your cells don't divide as they should. You can't prevent this abnormality from happening during cell division.

In which types of situations is the smallest unit rate the most desirable?
vekshin1

You should use the smallest unit rate any time accuracy is needed.  For example, if you are administering dosages of vaccines, you should use the smallest syringe possible for the dosage.  A smaller syringe will have more precise graduations than a larger one.  The same holds true for glassware such as graduated cylinders.  A 1000 ml graduated cylinder will probably not have a 5 ml graduation on it, and measuring out 5 ml with a cylinder that large would be guesswork at best.  A 10 ml graduated cylinder, however, will have graduations for every 0.1 ml, and would be suitable for measuring small amounts of liquids.
