What is the result when many chromosome mutations fail to separate properly?

If the chromosome mutations fail, then it is most likely to lead to a sign of cancer, since chromosome has failed to mutate properly.

Many chromosome mutations result when chromosomes fail to separate properly during what?
Meiosis, specifically during anaphase I and anaphase II. This is known as nondisjunction and it causes aneuploidy, such as trisomy 21
How do chromosome mutations affect an individual?
Chromosome mutations can result in changes in the number of chromosomes in a cell or changes in the structure of a chromosome. Unlike a gene mutation which alters a single gene or larger segment of DNA on a chromosome, chromosome mutations change and impact the entire chromosome.
Why are most mutations harmful?
Changes to DNA (mutation) are not necessarily harmful. Species are essentially a conglomeration of mutations which result a vast array of beneficial characteristics. Detrimental mutations generally result in death during early pregnancy, others may predispose an individual to death by cancer or disease at an early age and still others have a dramatic effect on the life of the affected individuals. Breeds of domestic animals are great examples of how many mutations there are within a species that are not specifically harmful. (There are over 500 breeds of dog for example.)

What do Multifactoral Disorders usually result from?

Which process could result in the type of cell mutation that causes Down syndrome?
Down's syndrome is caused by trisomy of the 21st chromosome. This is mostly caused when the chromosome pair fails to separate properly (nondisjunction).
Is Huntingtons disease non disjunction?
No. Hemophilia is the result of any of a number of mutations such as reversals, translations, deletions, etc. These mutations need to have occurred in a very specific segment of the coding found on the X chromosome. The replication of that X chromosome however is unaffected with the exception that the mutation on it is replicated as well.
What percentage of cancers are estimated to result from mutations that are not inherited?
70% of cancers are estimated to result from mutations that are not inherited.
Can Edwards' syndrome be cured?
Down syndrome can't be cured because it isn't a disease, it's a genetic mutation. Persons with down syndrome have an extra 21st chromosome. There are genetic mutations which result in the body not supplying or handling nutrients, hormones, or other substances properly. Those, when detected at childbirth or even in-vitro (before childbirth) may be treatable by supplying missing substances so the body can thrive properly, Other mutations may require surgical procedures to treat a problem. Downs is different. It isn't just a change in an existing chromosome. It is a whole additional chromosome. It can involve physical issues such that a survival after birth may not be possible even with the most heroic medical and surgical procedures. Hopefully at some point in the future, we will have a better understanding of what is going on, why the extra chromosome is present and what to do about it.
What causes the abnormality in chromosome numbers in people with down syndrome?
It is most commonly caused by increased maternal age.Add: It is the result of nondisjunction of the 21st chromosome pair, in which the pair fails to separate, so that one cell gets an extra copy of chromosome 21.
How can mutations affect protein synthesis in cells What is the result?
Mutations can be a source of genetic
How are point mutations and frame shift mutations different?
Point Mutations always result in [causing] a frame-shift mutation so they are the same.
