The mutation that occurs is known as a deletion. When a chromosome breaks and a portion is removed before the fragments rejoin, it results in the loss of genetic material from that chromosome. This deletion can lead to disrupted gene function and may have various effects on the organism, depending on the genes affected and the size of the deleted segment.

What type of chromosomal mutation is wolf hirschhorn syndrome?
Wolf-Hirschhorn syndrome is primarily caused by a deletion of a portion of chromosome 4, specifically at the 4p16.3 region. This chromosomal mutation is classified as a deletion mutation, where a segment of the chromosome is missing, leading to the loss of genetic material. The syndrome is characterized by developmental delays, distinctive facial features, and other congenital anomalies.
Is breast cancer chromosomal mutation or gene mutation?
First of all, chromosomal mutations are gene mutations. Chromosomes can be thought of as lists of instructions for your cells to build life essential proteins and other basic functions. A chromosomal mutation occurs when a portion of a chromosome is changed in some way. A portion may be removed, flipped, or part of another chromosome may be inserted. In many cases this will have no effect on cell function, as the mutation occurred in an ignored portion of the chromosome. In most cases where the mutation occurs in an important portion of the chromosome, the cell simply dies. Cancer occurs when the mutation, instead of killing the cell, causes the cell to multiply, and consume body resources more faster than normal cells, overwhelming them.
Which is worse chromosome mutation or point mutation?
Chromosome mutations are generally considered more severe than point mutations because they involve changes in a larger portion of genetic material, potentially affecting multiple genes and leading to more significant impacts on an organism's phenotype. Point mutations, on the other hand, involve changes in a single nucleotide and may have smaller-scale effects.
What diagram models deletion in which a chromosomes breaks and a piece of DNA is lost?
A deletion mutation is best represented in a karyotype diagram, where a section of a chromosome is missing or deleted. This is shown as a gap or break in the chromosome. Alternatively, a chromosomal ideogram can also illustrate a deletion by displaying a portion of a chromosome missing or shortened.
Is digeorge syndrome dominant autosomal or sex-linked?
DiGeorge syndrome is not caused by a single gene mutation, but rather by a deletion of a portion of chromosome 22. It is not inherited in a simple Mendelian pattern like dominant autosomal or sex-linked traits.
What are three types of chromosomal mutations?
Insertion, Deletion and Frameshift mutation. These are the 3 basic types of mutation, however, there are other types of mutations: substitution, translocation, duplication, inversion, transversion and transition.

Cancer begins when what damages a portion of what in a chromosome?
When something damages a portion of the DNA in a chromosome.

What is reciprocal mutation?
when there is a two way exchange of genetic portion between two non-homologus chromosomes, its called reciprocal mutation, its a type of translocation mutation

Mutation that occurs at the chromosome level resulting in changes in the gene distribution?
Chromosomal mutationAneuploidyAneuploidy 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. DeletionChromosome 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. DuplicationChromosome 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. InversionChromosome 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. InsertionChromosome 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. TranslocationThere 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 portion of the human Y chromosome is homologous to the human X chromosome?
The pseudoautosomal regions (PARs) at the tips of the Y chromosome are homologous to regions on the X chromosome. These PARs are responsible for pairing and recombination between the X and Y chromosomes during meiosis. About 5% of the Y chromosome is homologous to the X chromosome in humans.
