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...
Sheri, you have planned more stuff for your kids and you, almost 10 times over Phil. Why can't he? no idea.
ReplyDeleteyou're right though, Sheri, sometimes it requires two sets of eyes. yours are better than his. ohhh, he's just one man show. idk.
ReplyDeletewhen you do cleaning, Phil, you do a half ass job, what about all around the sink, behind things, all of the counter, I'd sooner I did it, plus you waste too much water. what a bathroom, Phil. what about getting on your hands and knees and scrubbing with a thick appliance brush the carpets. "you haven't done that in months." ah huh, you haven't done it once!
ReplyDeleteyou remember what you weren't told about over-cleaning in the 50's. everybody was getting sick a lot.
ReplyDeletenot only that, Sheri, it's bad for the environment.
