Its is a chromosomal mutation in which during the duplication the segment is repeated. For example, segments segregated as A B C D E- F G H when duplicated will be A B C B C D E-F G H where segment b and c are duplicated. Duplication categorizes under an error of replication.
Duplication of genes is a process in which a gene or a set of genes is replicated within a genome, leading to additional copies of the gene(s). This can happen through various mechanisms, such as unequal crossing over during meiosis or retrotransposition. Gene duplication can contribute to genetic diversity and evolution by allowing redundant copies of genes to diverge and potentially acquire new functions.
Genes can be duplicated due to errors in meiosis such as slippage during DNA replication or the activities of transposable
elements.
Gene duplications that do not have severe effects can persist over generations.
A set of genes must be duplicated before cell division can occur. This is called Replication.

What is it called when a segment of a chromosome is repeated?
It is called a gene duplication event. This can lead to the presence of extra copies of a particular gene or genes, which can have various effects on an organism's traits and evolution.
What is thought to be the significance of the duplication of homeotic genes?
The duplication of homeotic genes provides redundancy and flexibility in controlling developmental processes. It allows for genetic variation and evolution by providing opportunities for new gene functions to arise.
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 is the evolutionary significance of duplication?
Duplication can lead to the evolution of new genes with novel functions or regulatory patterns. It provides genetic redundancy that can buffer against deleterious mutations, offering evolutionary flexibility and facilitating the evolution of complex traits. Additionally, duplicated genes can diverge in function, contributing to genetic innovation and adaptation in response to changing environments.
What Variations of homologous genes that result in differences in structure and function are?
These variations are called paralogs. Paralogs are genes that arise from gene duplication events and can evolve to perform different functions. Despite their structural similarities, paralogs can have distinct roles in biological processes.

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.
How do different organisms have the same subset of genes?
Different organisms can have the same subset of genes through processes like gene duplication, vertical gene transfer, and lateral gene transfer. Gene duplication can lead to multiple copies of the same gene in different organisms. Vertical gene transfer involves the inheritance of genes from a common ancestor. Lateral gene transfer allows organisms to acquire genes from other species, leading to the sharing of genetic material among organisms.

Additionally, duplicated genes can diverge in function, contributing to genetic innovation and adaptation in response to changing environments.
How does duplication affect the organism?
Duplication can lead to genetic disorders, as extra copies of genes can disrupt normal cellular functions. It can also cause imbalances in gene expression, potentially leading to developmental abnormalities or predisposing an organism to disease. Additionally, duplication events can introduce genetic variability within a population, which may or may not be beneficial for the organism depending on the context.
What Variations of homologous genes that result in differences in structure and function are?
These variations are called paralogs. Paralogs are genes that arise from gene duplication events and can evolve to perform different functions. Despite their structural similarities, paralogs can have distinct roles in biological processes.
