Re: Off Topic 2014

So yesterday I just found out one of my students has deuteranopia (a form of color blindness). She actually wanted me to pick her brain for a while as I tested her on what certain colors were, etc. I've heard of people being color blind and such, but not in such a severe way where actual colors in any form are completely warped.

For the record, here's what her color spectrum could appear to be like:




And here is an example of what she possibly sees when she goes outside:




I understand color blindness is more common than I'm making it out to be (and there's a good chance a lot of you here probably also inherently have this), but this is the first person whom I've met that has it this severely.

I wonder if there's a way... some techy glasses or Photoshop or what have you... that I can distort a regular image so that those colors would make her colors look like our colors, so she knows what we see. I wonder if that makes sense.

I thought that color blindness could only be passed to males and that females could only be carriers. Is that not correct?

To just more rare in females.

Color blindness is a recessive trait thats attached to the X chromosome. So if a female were to inherit it from one parent she would have another X chromosome to back it up and not be color blind. She'd have to inherit color blindness from both parents to be colorblind. Males only have one X chromosome so if they inherit it from a parent there's no other X chromosome to become dominant.

I've got a good friend that's color blind and that's the way he explained things anyway. Maybe I'm wrong.

There are a lot of genes that go into seeing color, most of which are on the X chromosome. So it's not just one trait, but otherwise it's pretty much what you described. Women having two X chromosomes makes it much harder for them to inherit it.

What's crazy about the type of colorblindness she has is that it only happens in 0.1% of the female population.

That's actually only part of the story. Because females have 2 X chromosomes and males only have 1, there needs to be a mechanism to compensate for females having 2 copies of the X-linked genes while males only have 1 copy. That'w where X chromosome inactivation comes in. In females during a very early stage of development, one X chromosome is randomly inactivated with the same X remaining inactive in all descendants of that cell. The end result is that all females are essentially what are termed mosaics for the X chromosome with some cells having inactivated the X they inherited from their mother and other cells having inactivating the one they inherited from their father. If cells that would ultimately give rise to the retinal cone cells happen to inactivate the normal X, then the X with the mutant gene will be active and they would not produce a functional opsin protein in their retinas and the individual would be color-blind.

That makes more sense. OT comes through again!

South Korea, it's kind of fun. I just wish I had more than one half day to explore.

Re: Off Topic 2014

Sometimes when we play FIFA some of my friends complain if certain players (1P is red, 2P is blue, etc) are on the same team.

It's definitely pretty common. P

IIRC, on the demo I could change the color above to R/B/G/Y if I wanted to. Maybe it's for that very reason.

So my little cousin is being baptized this upcoming weekend and I'm the godfather...what kinds of gifts do you generally give for this kind of thing? I've never been to a baptism before lol.

I think you have to fulfill one of his requests on the day of your daughter's wedding. I'm pretty sure that's what Godfathers do.

Well, I have a 6 inch long tear in the left leg of my jeans, I lost my glasses, and apparently my friend found me passed out in my backyard. How was your night guys?

Played some 2K and slept in a bed. I think I did alright.

I lost my 5th game in a row in my Madden franchise, so I feel I do alright as well.
