Why are inversion mutations generally less harmful than deletions or duplications?
i think is due to the fact that there's no net loss of genetic information , it just a rearrangement of gene sequence , However, in individuals with an inversion there is an increased production of abnormal chromatids. This leads to lowered fertility due to production of unbalanced gametes .

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.
What are 2 types of mutaions?
Two types of mutations are point mutations, which involve changes to a single nucleotide in the DNA sequence, and chromosomal mutations, which involve changes to larger segments of DNA such as deletions, duplications, inversions, or translocations.
What is a chromosone mutation?
A chromosomal mutation is a change in the structure or number of chromosomes in an organism's cells. These mutations can result in genetic disorders or abnormalities due to alterations in the DNA sequence carried by the affected chromosomes. Examples include deletions, duplications, inversions, and translocations.
Why are insertions and deletions called frameshift mutations?
Insertions and deletions are called frameshift mutations because they shift the reading frame of the genetic code during protein synthesis, leading to a change in the sequence of amino acids in the resulting protein. This can have significant effects on the structure and function of the protein.
Any change or random error in DNA sequence?
A mutation is a change in the DNA sequence that can occur randomly or be induced by external factors. Mutations can range from a single nucleotide change to larger deletions or duplications. These changes can influence characteristics like protein structure and function, potentially leading to genetic disorders or other biological effects.
What are the four types of chromosomal mutations?
There are four different types of chromosomal mutations: Deletions, Translocations, Duplications and Inversions

What type of mutations create more change?
Deletions
What happens in Duplication?
Deletions and duplications of single-base pairs typically arise during homologous recombination and cause diseases. But what happens when a mutation occurs over multiple genes? Rearrangements of chromosomes include deletions of DNA sequences and duplications of segments, both of which can encompass thousands to hundreds of thousands of bases. Why do these large rearrangements occur? For one, certain structural features of the genome, also referred to as genome architecture, can render various regions fragile and thus prone to events such as chromosome breakage, which often result in translocations, deletions, and duplications. Often, these alterations happen due to errors during cell division when chromosomes align (Figure 1). Homologous recombination between areas of concentrated repeated sequences frequently creates deletions and duplications. Because they commonly involve more than one gene, the disorders caused by these large deletion and duplication mutations are often severe.
Is it true or false that mutations that result from the substitution of the nitrogen base for another are called deletions?
False. Mutations that result from the substitution of one nitrogen base for another are called substitutions, not deletions. Deletions involve the removal of one or more bases from the DNA sequence.
What process is responsible for abnormal karyotypes?
Abnormal karyotypes can result from processes such as chromosomal mutations, errors during meiosis or mitosis, exposure to mutagens, or genetic disorders. These processes can lead to changes in chromosome number (aneuploidy) or structure (translocations, deletions, duplications), resulting in abnormal karyotypes.
What does duplication mutation mean?
A duplication mutation is a type of genetic mutation where a segment of DNA is copied or repeated within a gene or chromosome. This can lead to an increase in the amount of genetic material, causing various effects on the individual's phenotype. Duplication mutations can play a role in genetic disorders and evolution.
What does insertion and inversion mutation have in common?
They are both mutations of chromosomes
What are the types of chromosomes mutations?
Duplication, translocation, inversion, deletion.
What is a chromosone mutation?
A chromosomal mutation is a change in the structure or number of chromosomes in an organism's cells. These mutations can result in genetic disorders or abnormalities due to alterations in the DNA sequence carried by the affected chromosomes. Examples include deletions, duplications, inversions, and translocations.
How many different kinds of mutations are there?
there are four different types of mutations. deletion, duplication, inversion, and translocation.
