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...
Deoge used to lay right in front of her water bowl when it was empty, and wait for mommy. never seen a dog so patient.
ReplyDeleteI'm letting Eclipse have full rein of the upstairs. I'm in my bedroom with Brewskie with the door shut. He's probably settled down out there and finally sleeping. just let him be for now, got food and water, nice big bed pillow.
ReplyDeletenot sure if Beth every knew, the Jonas brothers had a llasa-poo, and gave some many kudos. I think I heard that one a clip on the radio one time. if you're thinking about it, please get one. you won't be sorry.
