Just as the sperm may be donated, so may be the egg. Once the<br />

egg is fertilized, it can be implanted. <strong>The</strong> egg may be from a donor<br />

and implanted into the body <strong>of</strong> the woman seeking to raise the<br />

child, or it may be implanted in a surrogate who will then carry<br />

the fetus to term and give birth. Although the surrogate may have<br />

<br />

considerable effect on its health and well-being long after the birth.<br />

is the process <strong>of</strong> inserting mitochondria from<br />

one egg into another. <strong>The</strong> process is used to correct problems in a<br />

woman’s eggs if she wants to use her own eggs for IVF.<br />

Recall that there are two different kinds <strong>of</strong> DNA in all cells:<br />

the nuclear DNA inside the nucleus <strong>of</strong> the cell and the<br />

mitochondrial DNA outside <strong>of</strong> it. Although the nuclear DNA is<br />

the result <strong>of</strong> contributions from both parents, the mitochondrial<br />

DNA is passed completely from the mother to the child.<br />
