What happens when there is an error in the mechanisms by which chromosomes are passed down? what are some genetic disorders that can arise from mutations that are either inherited or acquired?

Gene mutations can be classified in two major ways: ... These mutationsare also called germline mutationsbecause they are present in the parent's egg or sperm cells, which are also called germ cells. When an egg and a sperm cell unite, the resulting fertilized egg cell receives DNA from both parents.
