The eye-color part of the article must not be factually correct, unless there have been some very recent developments in understanding genetic influence on eye color. Craig Venter, the first human being to have his genome sequenced, pointed out in interviews[1] that even after the sequencing, no one could tell for sure from the sequence that he has blue eyes. Just in the last day, an article following up on last week's American Society of Human Genetics conference[2] pointed out that genetic studies have continually overpromised and underdelivered, and there are still many very basic issues of human genetics that are embedded in deep uncertainty.
As the article kindly submitted here points out, people are already demanding designer babies. They used to try to get those by looking for sperm donations from the Nobel laureate sperm bank,[3] but that project had disappointing results, and the sperm bank is no longer in operation.
Researchers on human genetics I know locally (who analyze the data from the Minnesota Twin Families Study) use a photograph of two identical (monozygotic) twins from Germany[4] (from a different source, I think the original medical journal source, rather than the blog I link to here) to show that although genes are certainly very influential on human development, environment, including differing choices of lifestyle, matters too.
