What two types of chromosomal mutations?
Two are insertion mutations and deletion mutations.
What is the difference between gene and chromosomal mutation?
A gene mutation is a permanent change in the DNA sequence that makes up a gene. Mutations range in size from a single DNA building block (DNA base) to a large segment of a chromosome. A chromosomal mutation is a mutation involving a long segment of DNA, it is a any change in the structure or arrangement of the chromosomes. These mutations can involve deletions, insertions, or inversions of sections of DNA. In some cases, deleted sections may attach to other chromosomes, disrupting both the chromosomes that loses the DNA and the one that gains it.It is also referred to as a chromosomal rearrangement The differences between Gene mutation and Chromosome mutation are ; 1- Chromosome mutations involve changes in the structure of a chromosome OR the loss or gain of a chromosome while Gene mutations involve a change in the nucleotide -base sequence of a gene on a DNA molecule. 2- Chromosomal mutations are changes in the structure or the numbers of chromosomes (a gain or loss). Gene mutations involve changes in the nucleotide sequence of the DNA molecule. 3-A gene mutation is a permanent change in the DNA sequence that makes up a gene. Mutations range in size from a single DNA building block (DNA base) to a large segment of a chromosome while a chromosomal mutation is a mutation involving a long segment of DNA, it is a any change in the structure or arrangement of the chromosomes.

In some cases, deleted sections may attach to other chromosomes, disrupting both the chromosomes that loses the DNA and the one that gains it.It is also referred to as a chromosomal rearrangement 4-gene mutation is just a substitute in any old random nucleotide for any old random nucleotide chromosome mutation is missing of chromosome or +1 chromosome (down's syndrome).
An inherited disease or disorder that is caused by a mutation in a gene or by a chromosomal defect?
There are many thousands of different mutations.
What is one way that changes occur in a DNA Sequence?
Mutations (point mutations, inversions, translocations...) cause changes in DNA Simply stated, a mistake made while DNA copies causes changes in DNA.
Is it true that only mutations in gametes can be passed from parent to offspring?
Gametic mutations occur in the cells of the gonads (which produce sperm and eggs) and may be inherited. There are two types of mutations that can occur in gamete cells: 1. Gene Mutations 2. Chromosomal Mutations
What are the four types of chromosomal mutations?
There are four different types of chromosomal mutations: Deletions, Translocations, Duplications and Inversions
What is observed in a karyotype?
A karyotype is basically a chart of the number and structure of chromosomes. They can reveal ploidy differences (missing or additional chromosomes such as trisomy 21) or chromosomal mutations (like inversions, deletions, translocations etc)
What are four-types of chromosomal mutations?
Four Types of Chromosomal Mutations include-Duplication-Translocation-Inversion-Deletion
What two types of chromosomal mutations?
Two are insertion mutations and deletion mutations.
Are asbestos considered a chemical mutagen responsible for chromosomal mutations?
Not necessarily chromosomal mutations. Asbestos types are considered mutagens in lung cells, but any chromosomal mutation would have to be carefully engineered.
What are chromosomal changes which involve gene-orientation but do not result in gene expression changes called?
inversions
What are the various kinds of mutations?
Mutations differ and change according to many factors: 1- Site of occurrence: -Genetic mutations -Chromosomal mutations 2- The inheritance: -Somatic mutations -Gamete mutations 3- The origin: -Spontaneous (natural) mutations -Induced mutations 4- The harmful OR useful effects: -Undesirable mutations -Desirable mutations
Are chromosomal mutations more common in plants or animal?
chromosomal mutations can happen in any organism, but they are specially common in plants. Edited answer: Chromosomal mutations are more common in plants because plants remain seated at one place receiving all short of radiations and temperature range.
Where are chromosomal mutations commonly found?
in the cells, during meiosis.
Why is your DNA like no one else's?
Mutations and chromosomal crossover.
Why isn't there trisomy 5 or 17 in human population?
They are lethal chromosomal mutations.
