In Canada, a woman by the name of Melanie Boivin has arranged to have her eggs frozen so her daughter, who will probably be infertile, might have children.
The daughter, Flavie Boivin, cannot have children naturally because of a chromosomal condition called Turner syndrome.
Turner Syndrome:
A genetic condition that causes impaired growth and learning difficulties, destroys eggs, leading to an unusually early menopause.

If the daughter should decide to use the eggs will the child be Melanie Boivin’s child or grandchild and will it be Flavie’s child or sibling.
Assuming for the moment that the source of the sperm isn’t Flavie’s father she would be giving birth to her own half brother/sister.

Since this is a genetic condition, does it follow the male or female line?
Since the daughter already has it, won’t the use of her mother’s eggs increase the likelihood that her child may have it?

There exists in psychiatry a condition referred to as genealogical bewilderment, and any child born of this combination would definitely be the poster child.
