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.
What else can I help you with?
An error in DNA duplication is known as?
a mutation
What mutation involves two chromosomes?
Inversion and duplication!
How does mutation occur in the population?
Mutation can create new alleles, therfore can change allele frequencies in a population.
The mismatch of a DNA base pair during duplication can result in a mutation?
Yes, when a DNA base pair is mismatched during duplication, it can lead to a mutation in the DNA sequence. This can cause changes in the protein produced, potentially impacting the function of the gene and, ultimately, the organism.
The mismatch of a DNA base pair during duplication can result in a?
mutation in the DNA sequence. This can lead to genetic diversity and may have different outcomes, ranging from no effect to causing genetic disorders or diseases.

What is it called when a segment of a chromosome is repeated?
The mutation in which a segment of a chromosome is repeated is known as duplication.
What are different types of mutation?
Deletion, insertion, inversion, translocation, and duplication [for the ppl. Who dnt kno!!]

Which types of mutation can be add genes to a chromosome?
Gene duplication is a type of mutation that can add genes to a chromosome. During gene duplication, a segment of DNA is copied and inserted into the chromosome, leading to an increase in the number of copies of a particular gene. This can result in gene families with multiple copies of a gene that may evolve new functions over time.
What does genetogenesis mean?
"Genetogenesis" refers to the creation or formation of new genes through evolutionary processes such as mutation, recombination, or gene duplication. This term is often used in the context of studying genetic diversity and adaptation in populations over time.
Which is the single most important type of mutation that eventually allows for evolution via natural selection to occur?
gene duplication (might give advantages)
How can a dog breeder determine mutation by the hairlesseness?
Hairlessness in dogs is called genomia. It is a duplication mutation that appears in Chinese crested and Mexican Xoloitzcuintule breeds. The hairlessness trait is dominant, which means that it can express if the dog only has one parent with the trait.
One of the best pieces of evidence for the process of gene duplication followed by mutations is the occurrence of?
Pseudogenes, which are non-functional copies of genes that have accumulated mutations over time, are a strong indicator of gene duplication followed by mutations. Pseudogenes often have similar sequences to functional genes but lack the ability to code for proteins, supporting the theory of gene duplication and divergence through mutation.
