gene transfer in eukaryotes
Gene transfer in eukaryotes may come in the form of mitosis or meiosis. However, horizontal gene transfer, to my knowledge, does not occur in euks.
Horizontal gene transfer is when a cell's DNA is transferred to an individual without reproduction. Bacteria have the ability to accept plasmids from other bacteria, and then incorporate the DNA in to their own genome.
Horizontal gene transfer, the transfer of genetic material between organisms without direct parent-to-offspring inheritance, is considered rare in humans. However, there is evidence suggesting that it has occurred in our evolutionary history, particularly with ancient viruses that have incorporated their DNA into the human genome. Despite these occurrences, horizontal gene transfer is not a significant mechanism for genetic change in humans compared to vertical gene transfer from parent to offspring.

Which process occurred frequently in the early history of the three domains on Earth and makes determining phylogenetic relationships of that time difficult?
Horizontal gene transfer occurred frequently in the early history of the three domains on Earth, making it difficult to determine phylogenetic relationships. This process involves the transfer of genetic material between different organisms, blurring the evolutionary history of organisms and complicating the tracing of their genetic lineages.
What is the primary source of genetic variability in prokaryotes?
The primary source of genetic variability in prokaryotes is through horizontal gene transfer mechanisms such as transformation, transduction, and conjugation. These processes allow prokaryotes to acquire new genetic material from other bacterial cells or environments, leading to genetic diversity within populations.
What gene indicates that yeasts and humans share a common ancestor?
The gene that indicates yeasts and humans share a common ancestor is the ribosomal RNA gene. This gene is highly conserved across different species and is used in phylogenetic studies to understand evolutionary relationships. By comparing the sequence of this gene in yeasts and humans, scientists have been able to demonstrate their shared ancestry.
How does bacteria increase genetic variation?
Bacteria increase genetic variation through mechanisms such as mutation, horizontal gene transfer, and genetic recombination. Mutations can introduce new genetic variations, while horizontal gene transfer allows bacteria to exchange genetic material with other bacteria and acquire new genes. Genetic recombination, through processes like conjugation and transformation, also contributes to genetic diversity in bacteria.
What is a self-transmissible plasmid?
A self-transmissible plasmid is a type of plasmid that can transfer genetic material from one bacterium to another through a process called conjugation. This plasmid carries the necessary genes for forming a conjugative pilus and transferring the plasmid DNA. Self-transmissible plasmids play a significant role in horizontal gene transfer among bacteria.
What is the difference between horizontal gene transfer and vertical gene transfer?
Horizontal gene transfer involves the transfer of genetic material between different organisms, such as bacteria exchanging genes through processes like transformation, transduction, or conjugation. Vertical gene transfer refers to the transmission of genes from parents to offspring, typically through sexual reproduction in eukaryotic organisms.
What term is used for the transfer of a gene from one organism to another?
Horizontal Gene Transfer is probably the term you are looking for
How can you became Spider-Man?
Get bitten by a radioactive spider. There is a possibility of horizontal gene transfer.
What are some key differences between horizintal gene transfer gene transfer and vertical descent with mutation?
Horizontal gene transfer involves the transfer of genetic material between different species, while vertical descent with mutation involves the passing on of genetic material from parent to offspring within the same species. Horizontal gene transfer can lead to rapid acquisition of new traits, while vertical descent with mutation is a slower process that drives evolutionary changes over generations within a species. Horizontal gene transfer can introduce genetic diversity quickly, while vertical descent with mutation helps in maintaining genetic stability within a species.
What is a xenologue?
A xenologue (also xenolog) is a gene sequence in which similar sequences can be found in different species, due to horizontal gene transfer.
When scientist transfer genes from one organism to the other it is called?
Horizontal and vertical gene transfers are the terms to account for the transfer of genes between organisms. Horizontal (HGT) or (LGT) transfer happens when non-traditional reproduction effectuates the transfer whereas vertical transfer (VGT) occurs when asexual or sexual reproduction effectuates the genetic movement from parents to offspring.
What is gene transfer through embryo injection?
the transfer of gene to the embryo in order to produce transgenic offspring is known as gene transfer through embryo.
What is agrobacterium mediated gene transfer?
transfer of gene with the help of Ti plasmid present in Agrobacterium which has T-dna region by which gene van transfer.
When a gene transfer to a person then what happen to other person?
when a gene transfer to a person then other person is scared of the gene
Why should you care about a resistant strain of tb in russia?
Aside from the fact of its spreading here, bacteria conjugate in horizontal gene transfer from one type of TB bacillus to another.

Is sexual or asexual better?
Asexual reproduction is favourable if horizontal gene transfer can make up for the lack of diversity within species. Horizontal gene transfer is when two mature organisms can switch or share different genes. (Many bacteria and archea can do this) Horizontal gene transfer is quite difficult for multi-cellular organisms, so sexual reproduction is preferable. The goal of reproduction is to create offspring that will survive in changing environment - so there must be a mechanism to create many different kinds of offspring. Sexual reproduction affords this. However - the optimal form of reproduction is to have the choice to reproduce either asexually and sexually. If there is a disaster (for humans) or a new antibiotic (for bacteria) it may be preferable to reproduce asexually for a while if no other similar species are around. Later, when the population is big enough, sexual reproduction can begin to recover genetic diversity. (I am assuming that clones don't reproduce with themselves the whole time). This may be the new and improved 'bisexual' of the future.
