Yes. What do I learn first?

I'll tell you the first thing I learnt:
Female's genetics are XX.
Male's genetics are XY.
Because the female's genetics can be the same, you could have
two copies of the same colour. For example, in a cat, you could
have a dominant red gene and a recessive red gene. The recessive
red will fade to black, and the dominant red will stay red, thus
creating the tortoiseshell pattern.
With males it's different. Because the genetics are two
different branches ~ X and Y ~ they must be different colours
and cannot be copies of each other. So it's almost impossible to
have a recessive red and a dominant red because they can't be
the same, which is why it's rare to find tortoiseshell toms.
Am I going too fast, or do you understand? I can break it down
further if you don't get it :)

Yeah, I get it. That explains why there aren't tortie toms and
stuff. So if the female's genes were dominant blue and recessive
blue, the recessive one would fade to black or whatever and
create the blue tortie pattern?

Yeah, pretty much. But...
There are some toms with XX genes, but one of the genes have
traces of the Y chromosome, making them male felines who can
have the tortie pattern. Confusing, but it's possible and has
been proved, which is why some male cats have tortoiseshell or
calico patterns.

Ok, I suppose that makes sense. Weird and unnatural though. XD

Now we'll start with genetics, and we'll start with a brown
tabby x brown tabby.
Well, of course some of the kits will be brown tabbies. But here
~ and I have no real way to explain this ~ there are different
options as well. Black is one of them, because the chromosomes
could be dominant black and recessive black, or in males a
dominant black and a recessive blue/red which would fade to
black. Black is a colour available in most litters because of
this.
Then blue is another option, both solid and tabbies. This is
because blue is the diluted (lighter) version of black, sort of
like a watered-out gene, so this also becomes acceptable.
The eye colours are now anything realistic but blue. If one or
both of the parents have white on then, blue becomes an
available eye colour for kits with white on.
And then comes fur length. If one parent has long fur and the
other has short, then half the kits will be long furred. If both
parents have long fur, all the kits will have long fur.
So if someone asked for a brown tabby x brown tabby litter, then
the basic answer for two, short-furred, brown tabbies with no
white would be:
Brown tabby, solid black, solid blue, blue tabby.
^^ this is VERY confusing, so if you don't get it just say and
I'll simplify it.

...processing. XD
So, blue would be available in tabby form too, because the brown
tabbies are tabbies?
I get the fur lengths and eye color thing, but the availability
of black confuses me. So its just there, or do they have to be
carrying it?

Yes for the blue tabby part, it's because the parents are
tabbies.
Black normally occurs when we have a recessive colour such as
red, because when red has no need it will fade to the darkest
colour, black. Black is one of the most common colours, and it
isn't like the albino gene which we'll get onto later. Black is
basically the backup of all genes, so if you had a colour that
cannot retain dominance it would fade to black. It's just there
in most litters, so yeah.

Ok. Now I get it. This is finally making some sense to me.
