Yes. When a gene is duplicated you have one gene doing the job it was doing before and the possibility of the duplicated gene having a beneficial mutation and picking up a brand new job to do and making a newly beneficial protein. Of course if the mutation is deleterious that organism will not pass those genes on any further than progeny. Remember, only germline mutation are passed on to future generations.
What else can I help you with?
Which event describes a change where evolution has happened?
An allele frequency changes in a population.
What theory has been used to explain the pattern of rapid evolution that often occurs after a mass extinction event?
The theory of rapid evolution rather than over a very long time.
How would an adherent to punctuated equilibrium explain the lack of intermediate links in the fossil record?
Where are you people getting these ill posed questions? What level? Transitional forms! At the species level this would be explained as a rapid (geologically rapid) speciation event followed by years of stasis, where little morphological change is taking place.
Are fossils indirect evidence of evoution?
Fossils are like the clues the police use to solve a crime. Together they paint a picture of the truth - in this case the truth is evolution Each one tells a story. Like clues to a crime, where the police don't have to find a print of every footstep taken by a subject or confirm every thing that he did, the clues paint a logical outline of all the events around the crime. Like clues in a crime the police do not initially identify a person they want to pin the crime on and then seek to tie him to the event - they find a number of clues which identify potential subjects of interest. They then attempt to prove the relation of these suspects to the crime until the trail of evidence is strong and dependable. Usually multiple facts on the same evidence are considered - for a crime it might be fingerprints and video tape and eye witnesses, for fossils it could be carbon 14 and dendrochronology and geologic strata.
What did Charles Dawin do to become famous?
Darwin was the naturalist aboard the Beagle and became somewhat feted by the scientific community on publication of his report of the voyage; Darwin was a good writer. Darwin lacked confidence as he hadn't had formal training as a scientist (he'd studied theology at university) and to feel more secure in his new career he studied barnicles - he became an authority on barnicles as a result.The key event in Darwin's life which made him famous outside of the scientific world was the publication of On the Origin of the Species in 1959. The book was a Victorian bestseller and it sold out in one day and Darwin became the most celebrated naturalist of his age.
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 is a species threatening event?
A species threatening event is just simply what the words themselves state, it is an event or occurance that potentially can harm or threaten species of animals native to the area being destroyed or tampered with.
According to the theory of punctuated equilibrium which event could lead to speciation?
A significant event, such as environmental change or isolation of a population, can lead to punctuated equilibrium and potentially trigger speciation. These rapid changes create new ecological niches, driving accelerated evolution and the emergence of new species.
What is the difference between paralogues and orthologues in terms of gene evolution and function?
Paralogues are genes that arise from a gene duplication event within the same species, leading to similar but not identical functions. Orthologues, on the other hand, are genes that are derived from a common ancestor and are found in different species, often retaining the same function. This difference in origin affects how paralogues and orthologues evolve and function in organisms.
What is the relationship between divergence and amplification?
Gene duplication (or chromosomal duplication or gene amplification) is any duplication of a region of DNA that contains a gene; it may occur as an error in homologous recombination, a retrotransposition event, or duplication of an entire chromosome.
The evolution of ancestral species into an array of many spices that occupy diffret habitats?
A radiation event. Called adaptive radiation.
Autopolyploidy is a speciation process that begins with an event during?
Autopolyploidy is a speciation process that begins with an event during which an organism has extra sets of chromosomes derived from the same species. This can occur through mechanisms such as whole genome duplication. These additional sets of chromosomes can lead to reproductive isolation and eventually result in the formation of a new species.
Charles Darwin's most important event of his life?
Charles Darwin's most important event is the publication of his groundbreaking work "On the Origin of Species" in 1859. This book introduced the theory of evolution by natural selection, revolutionizing our understanding of biology and the natural world.
Can you define paralogs and explain their significance in genetic research?
Paralogs are genes that are related through a gene duplication event. They have similar sequences but may have different functions. In genetic research, paralogs are important for understanding gene evolution, gene function, and genetic diversity within a species. They can provide insights into how genes have evolved and diversified over time, and how they contribute to different biological processes.
How does extinction drive evolution?
A mass extinction event creates a large gap in the biodiversity of an ecosystem or multiple ecosystems, which results in a rapid period of evolution of a range of different species that weren't particularly specialised to fill that niche.
Can you provide an example that distinguishes between orthologs and paralogs in terms of their evolutionary relationship?
Orthologs are genes in different species that evolved from a common ancestral gene through speciation, while paralogs are genes within the same species that evolved from a gene duplication event. For example, the gene for insulin in humans and mice is an ortholog, as it originated from a common ancestor. On the other hand, the multiple copies of the gene for hemoglobin within the human genome are paralogs, as they arose from gene duplication events within the same species.
What is the paralog definition in biology and how does it differ from orthologs?
In biology, paralogs are genes that are related through a gene duplication event within the same species. They have similar functions but may have diverged over time. Orthologs, on the other hand, are genes that are related through speciation events and are found in different species. They typically have the same function.
