Which type of mutation affects more genes, a gene mutation or a chromosomal mutation? Report Abuse. Chromosomal mutations include deletions or amplifications of large areas of a chromosome as well as inversions and translocations. Since chromosomes have many genes, a mutation to a chromosome could affect more genes than would a mutation to a single gene.bradlepe · 6 years ago. Thumbs up.ating Newest Oldest. Best Answer: Chromosomal mutations affect large regions of the chromosome, which may contain hundreds or thousands of genes. A gene mutation affects one gene. Thus, a chromosomal mutation will affect more genes.

How Gene Mutation Works Mutations cause changes in the genetic code that lead to genetic variation and the potential to develop disease. Gene mutations can be generally categorized into two types: point mutations and base-pair insertions or deletions. Point mutations are the most common type of gene mutation.

How can gene mutations affect health and development? A condition caused by mutations in one or more genes is called a genetic disorder. In some cases, gene mutations are so severe that they prevent an embryo from surviving until birth. These changes occur in genes that are essential for development, and often disrupt the development of an embryo in its earliest stages.ecause these mutations have very serious effects, they are incompatible with life. It is important to note that genes themselves do not cause disease—genetic disorders are caused by mutations that make a gene function improperly.

How Gene Mutation Works 1 Silent Mutation: Although a change in the DNA sequence occurs, this type of mutation does not change the protein that is to be produced. 2  This is because multiple genetic codons can encode for the same amino acid. 3  Amino acids are coded for by three nucleotide sets called codons.ene mutations are most commonly caused as a result of two types of occurrences. Environmental factors such as chemicals, radiation, and ultraviolet light from the sun can cause mutations. These mutagens alter DNA by changing nucleotide bases and can even change the shape of DNA.

- Gene mutations have varying effects on health, depending on where they occur and whether they alter the function of essential proteins. The types of mutations include: Missense mutation. This type of mutation is a change in one DNA base pair that results in the substitution of one amino acid for another in the protein made by a gene. Nonsense mutation

How do gene mutations and chromosomal mutations differ from each other? Gene mutation may lead to alter the number or the structure of the entire chromosome, which could lead to chromosomal mutations. However, gene mutations are small-scale alterations in the nucleotide sequence and those are sometimes corrected through gene regulatory mechanisms but sometimes not.ome of the problems that are evident of a gene mutation cause are the sickle cell anaemia and lactose intolerance. Chromosome Mutation. Chromosome mutation is a large-scale alteration of the chromosomes of an organism, where either the number or the structure of chromosomes is changed.

Chromosomes Chromosomal mutations produce changes in whole chromosomes (more than one gene) or in the number of chromosomes present. 1  Deletion- loss of part of a chromosome. 2  Duplication- extra copies of a part of a chromosome. 3  Inversion- reverse the direction of a part of a chromosome.

How do gene mutations and chromosomal mutations differ from each other? Gene Mutation. Gene mutation is a small-scale alteration of the genetic material of an organism, which primarily is a change in the nucleotide sequence of a particular gene. These changes are of two types based on the way those take place.ome of the problems that are evident of a gene mutation cause are the sickle cell anaemia and lactose intolerance. Chromosome Mutation. Chromosome mutation is a large-scale alteration of the chromosomes of an organism, where either the number or the structure of chromosomes is changed.

Types of Gene Mutations - Diseases Caused By Gene Mutation Such types of mutations are also called as mosaicism. Here are some diseases which are caused by gene mutations:- 1)Cystic Fibrosis:- Cystic fibrosis is a single gene mutation. This disease is related with secretory glands of the body like sweat and mucus.This is a hereditary disease.ene mutations vary from a small portion of the DNA molecule to a large part of chromosome. There are two types of mutations mainly: 1) Hereditary mutations:- This kind of gene mutations are hereditary that is they pass from parents to the off spring.

- Mutation can result in several different types of change in sequences. Mutations in genes can either have no effect, alter the product of a gene, or prevent the gene from functioning properly or completely.utations in the structure of genes can be classified as: , 1  such as those affecting a small gene in one or a few nucleotides, including: 2  Point mutations, often caused by chemicals or malfunction of DNA replication, exchange a single nucleotide for another. 3  These changes are classified as transitions or transversions.

How Gene Mutation Works Mutations can also occur in which nucleotide base pairs are inserted into or deleted from the original gene sequence. This type of gene mutation is dangerous because it alters the template from which amino acids are read. Nonsense Mutation: This type of mutation alters the nucleotide sequence so that a stop codon is coded for in place of an amino acid. 2  A stop codon signals the end of the translation process and stops protein production.

Difference Between Mutation and Polymorphism Mutations can be chromosomal mutations or gene mutations. Chromosomal mutation is a type of mutation that involve in the change of chromosome number. This takes place due to errors taking place during segregation of chromosomes in meiosis.

What is a gene mutation and how do mutations occur? A gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people. Mutations range in size; they can affect anywhere from a single DNA building block (base pair) to a large segment of a chromosome that includes multiple genes.hese genetic changes are not present in a parent’s egg or sperm cells, or in the fertilized egg, but happen a bit later when the embryo includes several cells. As all the cells divide during growth and development, cells that arise from the cell with the altered gene will have the mutation, while other cells will not.

Frameshift mutation Due to the triplet nature of gene expression by codons, the insertion or deletion can change the reading frame (the grouping of the codons), resulting in a completely different translation from the original. The earlier in the sequence the deletion or insertion occurs, the more altered the protein.A frameshift mutation is not the same as a single-nucleotide polymorphism in which a nucleotide is replaced, rather than inserted or deleted.A frameshift mutation will in general cause the reading of the codons after the mutation to code for different amino acids.ue to the triplet nature of gene expression by codons, the insertion or deletion can change the reading frame (the grouping of the codons), resulting in a completely different translation from the original. The earlier in the sequence the deletion or insertion occurs, the more altered the protein.
