Cat twins. . did you know? A cat can be its ewe twin when two fertilized eggs fuse together. And the result is this:. Actually that's not true. If two fertilized eggs fuse together the fetus will die because it will have too many chromosomes. The reason the cat is colored like

Actually that's not true. If two fertilized eggs fuse together the fetus will die because it will have too many chromosomes. The reason the cat is colored like that is due to x-inactivation. The genes that code for fur color are located on the X chromosome. In a female, 2 X chromosomes exist but during fetus development one X is inactivated in every cell permanently (and all its daughter cells) which causes genes on that chromosomes to be no longer expressed. So if the cat inherits one color from one parent and another color from the other, it can cause different colored fur like in the picture.

It's true, it's been documented in many animals, including humans. It's not that they fuse into one cell, it's that the cells join into one animal. Essentially, it's a graft that occurs in the womb. It has to happen before any significant cellular differentiation occurs, which is why it is so rare. And it's hard to detect, most candidates for this condition have pigment differences in either their hair, eyes, or skin. It's called chimerism if you feel the need to Google it.
#167 to #119 - bavmann (12/27/2012) [-]
Yes Chimeras can exist by 2 eggs getting fertilized and forming 1 organism, but that's extremely rare and it has been well documented that mosaicism in cats is caused by x-inactivation.

Oh, believe me it's possible, it's called 'Chimeraism'. But the wording of the content is a bit skewed, it's not that they 'fuse', but that both sets of DNA are able to co-exist. Look up the story of 'Lydia Fairchild', for example.

By what you're saying, it's caused by "x-inactivation". But if the X chromosome granted by the mother is inactive, wouldn't it be albino or take after the father?
User avatar #156 to #153 - imapatheticbanana (12/27/2012) [-]
You're forgetting that the X chromosome is only 1 of the 23 pairs of chromosomes a human has. So yes, it would take after the father in the genes that are specifically related to the X Chromsome. However, it is random in every cell, so it is a 50% chance for either X Chromsome to condense.
User avatar #160 to #156 - Conquistador (12/27/2012) [-]
You're forgetting we're talking about cats. And based on what he said, the x chromosome is responsible for fur color.
User avatar #162 to #160 - imapatheticbanana (12/27/2012) [-]
No I'm not. The fur color is a gene specifically on the X Chromosome.
User avatar #169 to #162 - Conquistador (12/27/2012) [-]
Most of what you say doesn't even make sense.
User avatar #164 to #160 - imapatheticbanana (12/27/2012) [-]
"it would take after the father in the genes that are specifically related to the X Chromsome" read what I said.
User avatar #168 to #164 - Conquistador (12/27/2012) [-]
First of all, that guy threw me off because he said the x chromosome is responsible for fur color. But I pretty much figured out what he was trying to say. The x chromosome is responsible for certain alleles that determine certain colors such as black or orange.
User avatar #173 to #168 - imapatheticbanana (12/27/2012) [-]
Okay I'll try to break it down for you.
So in cats, the gene for fur color are X-Related, meaning they are on the X Chromosome. This being, because males only get one X (from their mom), they will have the same fur color as their mother. The gene is not on the Y Chromosome.
However, females are different. They have two X's, and in each cell, one of them condenses into a Barr Body and is therefore not expressed. It is random in which X condenses in cells, which results in different X Chromosomes being expressed in each cell. This results in the different fur colors in a cat. This is also why all Calico cats are female. Understand now?

You contradicted yourself earlier. "it would take after the father in the genes that are specifically related to the X Chromsome."

Having fun in that 9th grade biology class?

Sorry I was thinking how boys always take after their mothers in genes on the X Chromosomes. Disregard that..

And I'm in AP Biology mind you -.- I'm the only sophomore in it.
We don't go into this depth in regular biology.

"In cats, one of several genes controlling fur color is located on the X chromosome."
That was the point I was trying to get across.

Lol.
>Implying grades determine intelligence.
I was only in a small amount of AP **** , and I was still more intelligent than pretty much all the dumbasses in there.
User avatar #179 to #178 - imapatheticbanana (12/28/2012) [-]
How is that any different from what I said? lol

I didn't imply grades determine intelligence?
I just said Blooms Taxonomy, which shows how grades DON'T determine intelligence..
And anyway, one thing I like about AP Classes more than regular (which aren't even classes) is that the questions are all analytical and use application- not just memorization.
User avatar #181 to #179 - Conquistador (12/28/2012) [-]
You said the X chromosomes are responsible for fur color in general. When it's really "one of several".

Then why'd you bring up your position in class? To try to impress me?
Hahahaha, I put no real effort into AP and I still got high grades.
User avatar #182 to #180 - Conquistador (12/28/2012) [-]

The X-Inactivation is called a Barr Body. just saying.
