Chromosome mutations

Chromosome mutations are mutations in a chromosome. There are different kinds of mutations, some include the whole chromosome, while others only include pieces of a chromosome. Some examples are: mutations there parts of the chromosome get erased, mutations where parts are added to the chromosome. There is also a possibility that parts of the chromosome change places. These are all changes that include many genes. Some might be dangerous, some might not.

An example of a syndrome that exists due to chromosome mutations is Downs syndrom. The people who have downs syndrome have three chromosome pairs of chromosome pair 21. The third chromosome pair exists because while Meiosis happened there were egg cells created with an additional chromosome pair. When the 24 chromosome pairs from the egg cell melt together with the 23 chromosome pairs from the sperm cell, the human that gets formed, receives one additional chromosome pair.
