I read the article. Nowhere was it mentioned about the possibility of years down the road what happens if two of this woman's many children should meet and marry. They'd have no idea they were related. Pity their children.
Excellent point...Unfortunately, many fail to realize this.

The exact same "argument", such as it is, could be made against adoption...
Children meeting and marrying can also be an issue in other circumstances. Like a man in a small town who sleeps around on his wife in secrecy, impregnating some other women.
Also adopted children, from a woman who gives up multiple children through her life for adoption. I'm curious if we have some sort of built in defense against that. Imagine in a small nomadic tribe how big of an issue that could be, one of the men knocking up more then one woman 20 years before.
Most donor egg/sperm children grow up knowing their origins, just as adopted children do. Even today in 2006, DNA test kits with private mail order results are available for $100. Imagine what will be available in 20 years.
Well, I truly doubt that the 12 eggs she donated produced 12 children. I think less than 20% of these fertility treatments are sucessful, and usually than implant more than one embryo at a time.
The chances of two meeting is small. The chances of those two then procreating is even smaller. And the chances that they will have a common harmful recessive genotype is much, much, smaller. Combine these three improbabilities and you have odds that are so infinitesimal as to be statistically zero.
