The term is monosomy, in which one chromosome of a pair is missing. Turner's Syndrome is an example of monosomy, in which there is only one sex chromosome, which is the X chromosome. Humans with Turner's Syndrome are female, but sterile. The genotype of the sex chromosomes in Turner's Syndrome is XO, in which O represents a missing chromosome.

What involves the loss of all or part of a chromosome or one base?
The loss of all or part of a chromosome is known as a deletion mutation, which can result in various genetic disorders depending on the size and location of the deletion. A loss of a single base is referred to as a point mutation, specifically a deletion, which can alter the function of a gene by changing the protein it encodes. Both types of mutations can have significant effects on an organism's phenotype and can lead to diseases or developmental issues.
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.

A chromosome that is exposed to a mutagen breaks into two pieces. A portion off one of the ends is removed before the two pieces rejoin. The mutation that occurs is?
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.
How is Duchenne Muscular Dystrophy inherited monosomy or trisomy?
Duchenne affects approximately 1 in every 3500 boys, or 20,000 babies born each year worldwide. Because the Duchenne gene is on the X chromosome, the disorder manifests primarily in boys. In nearly 35% of cases, Duchenne is caused by random genetic mutation.
What is change in a chromosome involving reversal of a fragment of the chromosome?
A chromosome inversion is a type of structural change in a chromosome where a segment of DNA is reversed in orientation. This can lead to disruptions in gene expression and potential issues during cell division. Inversions can be balanced or unbalanced, depending on whether there is a loss or gain of genetic material.
What is the result of a mutation occurring in a suppressor gene?
A mutation in a suppressor gene can lead to the loss of its normal function, resulting in the inability to suppress the growth of cancer cells or prevent mutations from occurring. This can contribute to the development and progression of cancer.

Deletion is when a whole segment of a gene is?
Deletion occurs when a whole segment of a gene is lost.
What do the four types of chromosomal mutations do?
The four types of chromosomal mutation are deletion, duplication, inversion and trasnlocation. Deletion is the loss of all or part of a chromosome. Duplication is where a segment of a chromosome is copied. Inversion is where a section of a chromosome is reversed. Translocation is the process in where a part of one chromosome breaks off and attaches to a non-homologous chromosome.
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.
A change in a population gene pool due to a chance event?
The sudden change in the genetic make up or genetic form of an individual is called gene mutation.

What best describes chromosomal deletion?
Chromosomal deletion is a genetic mutation where a part of a chromosome is missing. This can lead to the loss of specific genes, which can cause genetic disorders and other health problems in individuals. Deletions can vary in size and can affect different parts of the chromosome.
What is change in a chromosome involving reversal of a fragment of the chromosome?
A chromosome inversion is a type of structural change in a chromosome where a segment of DNA is reversed in orientation. This can lead to disruptions in gene expression and potential issues during cell division. Inversions can be balanced or unbalanced, depending on whether there is a loss or gain of genetic material.
Is cystic fibrosis a mutation?
yes, it is caused by a mutation in the gene cystic fibrosis transmembrane conductance regulator (CFTR). The most common mutation, which results in a loss of the amino acid phenylalanine
What is a permanent change in the DNA sequence of a gene?
Basically change in the DNA sequence of a gene is associated with change in the nucleotide sequence which may result in Mutation and may cause loss of function of that particular mutated gene.
What broken part of a chromosome becomes attached to a nonhomologous chromosome with no molecular loss?
A broken part of a chromosome that becomes attached to a nonhomologous chromosome without molecular loss is known as a translocation. This can lead to genetic disorders if the translocated segment disrupts the function of important genes located on the chromosome.
