What is the genetic mutation "Originally, we all had brown eyes," said Professor Hans Eiberg from the Department of Cellular and Molecular Medicine. "But a genetic mutation affecting the OCA2 gene in our chromosomes resulted in the creation of a "switch," which literally "turned off" the ability to produce brown eyes." The OCA2 gene codes for the so-called P protein, which is involved in the production of melanin, the pigment that gives colour to our hair, eyes and skin. The "switch," which is located in the gene adjacent to OCA2 does not, however, turn off the gene entirely, but rather limits its action to reducing the production of melanin in the iris -- effectively "diluting" brown eyes to blue. The switch's effect on OCA2 is very specific therefore. If the OCA2 gene had been completely destroyed or turned off, human beings would be without melanin in their hair, eyes or skin colour -- a condition known as albinism...
even did when they had Special Olympics there one time, the upstairs track. some people may or may not have thought I was nuts. probably was.
ReplyDeletetypically Beth and me would always go out to eat in Iowa City too, after seeing the doc, but not always.
ReplyDeleteI believe my daughter is still going to I.C., and she's probably told me this a hundred, but I don't believe she held on to the tradition, the Field House. Good news is, I guess it's every 6 months now. yah!
