An egg donor’s role is essentially to provide genetic material to help someone else build a family when they can’t use their own eggs.
That usually means going through medical screening, hormone injections to stimulate egg production, and a retrieval procedure. Once the eggs are retrieved, the donor’s role is typically complete, the donor does not carry the pregnancy or have parental responsibilities unless a very specific, pre-agreed open arrangement exists.
What people often misunderstand is that egg donation isn’t just biological; it also involves informed consent, medical oversight, and emotional readiness. Donors need to understand how their eggs may be used, whether the donation is anonymous or open, and what level of future contact (if any) is possible.
Resources like YourEggs explain this well by breaking down the medical, legal, and emotional aspects of egg donation for both donors and recipients, which helps people make decisions without pressure or confusion.
In short: the egg donor contributes genetics, not parenthood, but clarity, ethics, and transparency matter a lot in how that role is defined.
What else can I help you with?
Why is it necessary to use an egg cell for cloning an animal Why can't you just use the donor cell from the adult animal?
Cloning an animal requires an egg cell because it provides the necessary cellular environment and factors that support the reprogramming of the donor nucleus from the adult animal. The egg cell contains specific cytoplasmic components that facilitate the development of the embryo, which are not present in somatic (donor) cells. Simply using the donor cell would not initiate the correct developmental processes needed for successful cloning. Thus, the egg cell acts as a crucial facilitator for the reactivation of the genetic material from the donor cell.
What has to be removed from the donor's egg during cloning?
The nucleus of the donor's egg, which contains the donor's genetic material, needs to be removed during the cloning process. This step is necessary to make room for the nucleus from a somatic cell, which will be inserted into the enucleated egg to create a cloned embryo.
What are the steps of nuclear transplantation?
Nuclear transplantation involves several key steps: First, a somatic cell is obtained from a donor organism, and its nucleus is removed. Next, an enucleated egg cell (an egg cell stripped of its nucleus) is prepared, and the donor nucleus is inserted into this egg cell. The egg is then stimulated to begin dividing, eventually developing into an embryo, which can be implanted into a surrogate mother for gestation. This technique is fundamental in cloning and regenerative medicine research.
What is the introduction of the nucleus from a body cell into an egg cell to generate an organism identical to the nucleus donor?
This process is called somatic cell nuclear transfer (SCNT). It involves transferring the nucleus of a body cell into an egg cell that has had its own nucleus removed. The resulting cell can develop into an organism identical to the nucleus donor.
Is there a way to take out the DNA in a donor egg and replace it with male DNA?
Yes, there is a technique known as nuclear transfer or somatic cell nuclear transfer (SCNT) that involves removing the nucleus, which contains the DNA, from a donor egg and replacing it with the nucleus from a male somatic cell. This process has been used in cloning studies, but it raises significant ethical and technical challenges. Additionally, the resulting embryo would contain only the male DNA and mitochondrial DNA from the egg donor, which is not the same as a complete genetic replacement.
What is the purpose of the egg cell donor in cloning?
The egg cell donor in cloning provides the genetic material necessary for the creation of a clone. The nucleus of the donor egg cell is usually removed and replaced with the DNA of the individual being cloned, initiating the development of a genetically identical organism. The egg cell provides the necessary environment for the DNA to develop into a new organism.
Do clones have the same age of the donor at birth?
No. Cloning is essentially taking an egg (somatic cell) from the donor and regrowing it in a cell with no nucleus.

Cloning an animal requires an egg cell because it provides the necessary cellular environment and factors that support the reprogramming of the donor nucleus from the adult animal.

In order to create an embryo from a somatic cell the donor egg cell must have its what removed?
In order to create an embryo from a somatic cell, the donor egg cell must have its nucleus removed. This process, known as enucleation, removes the genetic material of the egg, allowing the somatic cell's nucleus to be inserted into the egg. This technique is essential for cloning and certain reproductive technologies.
What has to be removed from the donor's egg during cloning?
The nucleus of the donor's egg, which contains the donor's genetic material, needs to be removed during the cloning process. This step is necessary to make room for the nucleus from a somatic cell, which will be inserted into the enucleated egg to create a cloned embryo.
Why is the nucleus removed from an egg cell at the mammal cloning process?
In the mammal cloning process, the nucleus is removed from an egg cell to eliminate the egg's genetic material, allowing for the introduction of a donor nucleus that contains the desired genetic information. This step is crucial as it creates a genetically uniform environment in the egg, enabling the development of an embryo that is a clone of the organism from which the donor nucleus was taken. By removing the nucleus, the egg cell can then be stimulated to divide and develop into a new organism using only the genetic material from the donor.
What is cloning and how does it work?
Cloning is creating an exact genetic copy of something. To clone first take the nucleus from a donor cell, and collect some unfertilized eggs. Remove and replace an egg nucleus with the donor cell nucleus, and put the egg in a womb, for it to be born.
What are the steps of nuclear transplantation?
Nuclear transplantation involves several key steps: First, a somatic cell is obtained from a donor organism, and its nucleus is removed. Next, an enucleated egg cell (an egg cell stripped of its nucleus) is prepared, and the donor nucleus is inserted into this egg cell. The egg is then stimulated to begin dividing, eventually developing into an embryo, which can be implanted into a surrogate mother for gestation. This technique is fundamental in cloning and regenerative medicine research.
What happens during cloning?
During cloning, a copy of an organism is created by taking a nucleus from a donor cell and inserting it into an egg cell that has had its nucleus removed. The egg cell with the donor cell's nucleus is then implanted into a surrogate mother where it can develop into a genetically identical organism. Cloning has been successfully used in animals but is still a complex and controversial process in humans.
What is the role of the somatic cell donor in cloning?
the clone will come out exactly just like the one who donated the somatic cell
What is the introduction of the nucleus from a body cell into an egg cell to generate an organism identical to the nucleus donor?
This process is called somatic cell nuclear transfer (SCNT). It involves transferring the nucleus of a body cell into an egg cell that has had its own nucleus removed. The resulting cell can develop into an organism identical to the nucleus donor.
How is cloning carried out?
Cloning is carried out by taking the genetic material from a donor cell and placing it into an egg cell that has had its genetic material removed. The egg is then stimulated to start dividing and developing into an embryo, which is then implanted into a surrogate mother to grow and develop into a genetically identical organism to the donor.
