Which is worse: chromosomal mutation or gene mutation?

Question

I didn't fully understand which my teacher said was worse. Which is worse/more harmful?

Answer 1

Chromosomal mutation covers more territory and would more likely lead to death of the individual. Gene mutation is a smaller effect.

Answer 2

Gene Mutations And Chromosomal Mutations

Answer 3

A gene mutation is an eternal replace contained in the DNA series that makes up a gene. Mutations vary length-wise from a unmarried DNA progression block (DNA base) to a wide phase of a chromosome. A chromosomal mutation is a mutation proper to a lengthy phase of DNA, that is a any replace contained in the shape or association of the chromosomes. those mutations can contain deletions, insertions, or inversions of sections of DNA. often times, deleted sections may connect to different chromosomes, disrupting both the chromosomes that loses the DNA and the single which positive aspects it.that is often referred to as a chromosomal rearrangement Neural tube defects (NTDs) are difficulty-loose beginning defects of the mind and spinal twine that comprise anencephaly and spina bifida (meningomyelocele). Deficiency of the diet folic acid will develop the probability of NTDs, as does mutation of a gene for an enzyme that approaches folic acid. The mutation is termed the C677T.those with 2 copies of the T mutation are 2 and a 0.5 cases as likely to have a NTD as those with 2 copies of the conventional gene. Now that is been found that those with purely one reproduction of the T gene are also at more effective probability for an NTD. they're one and a 0.5 cases extra likely to have a NTD than those with 2 copies of the conventional gene. there is information that some moms of little ones with Down's syndrome have odd metabolism of folate and methyl, to boot as mutations in folate genes, that are valuable factors that are also considered in neural-tube defects (NTD).!!

Answer 4

In one sense, chromosomal mutations are worse if you're thinking about things like deletions. That's because you may be losing a bunch of genes.

However there are many many single gene mutations which are lethal, so it's kind of a toss-up.
