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.
The mutation in which a segment of a chromosome is repeated is known as duplication.
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.
Paralogs are genes that are related through gene duplication within the same species. They differ from orthologs, which are genes that are related through speciation events, and homologs, which are genes that share a common evolutionary origin.
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.
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.

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.
Paralogs are genes that are related through gene duplication within the same species. They differ from orthologs, which are genes that are related through speciation events, and homologs, which are genes that share a common evolutionary origin.
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.

Orthologous genes are genes that originated from a common ancestor and diverged due to speciation, while paralogous genes are genes that originated from gene duplication within the same species and diverged due to mutations. Orthologous genes have similar functions in different species, while paralogous genes may have different functions within the same species.
