Mutation that occurs at the chromosome level resulting in changes in the gene distribution?
Chromosomal mutation
AneuploidyAneuploidy occurs when a cell has the wrong number of chromosomes either due to an extra or missing chromosome. This type of problem can occur during the anaphase part of M phase. Through a process called nondisjunction the chromosome pairs may not separate properly causing one of the daughter cells to receive both copies of a chromosome and the other daughter cell receives no copies of that chromosome. Therefore, one daughter cell will have an extra chromosome and the other daughter cell will have a missing chromosome. Also, this problem can occur if there is a lag during anaphase. When the pairs of chromosomes separate to each side of the cell, a chromosome may travel too slow which would cause it to not be incorporated into the new cell. This new cell would be missing a chromosome.Deletion
Chromosome Deletions occur when the cell is missing a portion of a chromosome. This type of problem can occur during S phase if there is a problem during DNA replication or other parts of interphase if the DNA is damaged.Duplication
Chromosome Duplications occur when a cell has a repeated portion of a chromosome which causes the cell to have extra information. This type of problem can occur during S phase if there is a problem during DNA replication.Inversion
Chromosome Inversions occur when a piece of a chromosome breaks and that piece is reattached in the opposite orientation. This type of problem can occur during interphase if the DNA is exposed to damage that causes DNA breakage.Insertion
Chromosome Insertions occur when a piece of a chromosome that had broken reattaches in a location where this genetic material is not typically found. This type of problem can occur during interphase if the DNA is broken and then repaired by attaching to a different location.Translocation
There are two types of translocations: reciprocal and robertsonian. A reciprocal translocation occurs when two nonhomologous chromosomes break and then switch genetic material. A robertsonian translocation occurs when two chromosomes break on the p arm near the centromere and then the two q arms attach together while the p arms are lost. Either of these types of translocation can occur at any point during the cell cycle.
What else can I help you with?
A mutation caused by a piece of DNA breaking away from its chromosome and becoming attached to a nonhomologous chromosome is called?
This type of mutation is called a translocation mutation. It involves the movement of a segment of DNA from one chromosome to another non-homologous chromosome, leading to potential genetic changes and abnormalities.
Which of the following could be described as a chromosomal mutation?
A deletion, inversion, or translocation of a chromosome would be considered chromosomal mutations. These alterations involve changes in the structure or number of chromosomes, leading to genetic variations and potential health consequences.
A chromosome that has been broken and rejoined in a reversal sequence has undergone?
A chromosome that has been broken and rejoined in a reversal sequence has undergone an inversion mutation. This can lead to changes in gene expression and potentially affect the phenotype of an organism.
How are chromosomal mutations different than DNA mutations?
a gene mutation can be acquired throughout life or it is genetic ex sickle cell anemia chromsome mutations have more pronounced effects and are due to a change in the number of chromosomes or a change in the structural effect that are inherited.. ex downs syndrom
Mutations that change one or just a few of nucleotides in a gene on a chromosome are called what?
the correct answer is C. a substitution i know this cause i have this book to this question and point mutation is not one of the answer and i found the answer in the book -No its substituton you jack wagon your books wrong
How do chromosome mutation bring evolutionary changes?

What mutation cause changes in the number of chromosome?
Aneuploidy mutation causes a change in the number of chromosomes. Aneuploidy occurs during cell division when the chromosomes do not separate properly resulting in a change in the number of chromosomes.
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.
What is the definition of chromosome mutation?
A chromosome is an organized structure of DNA and protein that is found in cells.In biology, mutations are changes to the nucleotide sequence of the genetic material of an organism.
A mutation caused by a piece of DNA breaking away from its chromosome and becoming attached to a nonhomologous chromosome is called?
This type of mutation is called a translocation mutation. It involves the movement of a segment of DNA from one chromosome to another non-homologous chromosome, leading to potential genetic changes and abnormalities.
Could a mutation in a cell in the liver of a human be passed on?
For a mutation to be passed onto the next generation it must be on sex chromosome. If mutation occurs in somatic cells of our body, it will not be passed on to the offspring(s). Mutation that changes one or few base pairs in the DNA is called point mutation.
Any permanent change in gene or chromosome of a cell?
A mutation is a permanent change in the gene or chromosome of a cell that can result in altered characteristics or function. Mutations can arise spontaneously during cell division or in response to external factors such as radiation or chemicals. These changes can be inherited or occur randomly in somatic cells.
Which of the following could be described as a chromosomal mutation?
A deletion, inversion, or translocation of a chromosome would be considered chromosomal mutations. These alterations involve changes in the structure or number of chromosomes, leading to genetic variations and potential health consequences.
What chromosomes are responsible for dwarfism?
Some studies have isolated defects for the production of pituitary hormones to the short arm (the "p" end) of chromosome 3 at a specific location of 3p11. Other studies have found changes on the short arm of chromosome 7.
What are 4 types of chromosome structural changes?
The four types of alterations of chromosome structure are deletion, duplication, inversion, and reciprocal translocation. Deletion is the loss of one or more nucleotides from a gene by mutation; the loss of a fragment of a chromosome. Duplication is repition of a part of a chromosome resulting from fusion with a fragment froma homologous chromosome. Duplication can result from an error in meiosis or from mutagenesis. Inversion is a change in a chromosomeresulting from reattachment of a chromosome fragment to the original chromosome, but in a reverse direction. Mutagens and errors during mesosis can cause inversions. Translocation is the attachment of a chromosomal fragment to a nonhomologous chromosome.
Chromosomal mutation resulting in alagille syndrome?
Alagille syndrome is predominately caused by changes in a gene called Jagged1 located on chromosome 20. The effects vary widely from severe Alagille syndrome, involving heart and liver disease, to others experiencing only minor manifestations.
A chromosome that has been broken and rejoined in a reversal sequence has undergone?
A chromosome that has been broken and rejoined in a reversal sequence has undergone an inversion mutation. This can lead to changes in gene expression and potentially affect the phenotype of an organism.
