if a cat has one gene for white and one gene for orange, what color is the cat????????????????????????????????

Answer 2

The red or orange gene
Unlike other coat color genes, the gene that determines red coloration can be carried only on the X chromosome. If you look at pictures of chromosomes (they look a bit like X-shaped breakfast cereal, with long arms), you will see that the X chromosome is normal sized in relation to other things, but the Y chromosome is smaller. It can't carry the gene that determines red color; only the X chromosome can do that.
The gene that determines red or orange coloration in cats is designated as O (for orange).

O = orange
o = non-orange

If the cat inherits an O pattern proper for its gender (I'll explain that in the following sections), the cat will be red or orange (I'll just continue to call it orange, even though most cat associations refer to this as red). This orange will cover up all other colors, except pure white. If the cat inherits an o pattern proper for its gender, it won't be orange.

Males and the O gene
Remember, however, that the Y gene can't carry the O gene at all -- only X can. Males are genetically XY. The Y fires a blank as far as the O gene is concerned, so males only get one O gene -- from Mom. The designation for this "blank" is usually just written as Y.
Male patterns:

OY = orange cat
oY = non-orange cat
These are the only possibilities for an XY cat.

Females and the O gene
Females get one X from each parent, so they get two O genes.
However, here's where things get exciting.

In most genes, the capital letter designation is for dominant genes, and the small letter designation is for recessive genes. In most genes, if the cat gets one dominant gene and one recessive gene, whatever is the dominant gene will show up and the recessive gene won't actually appear on the cat. The cat is said to "carry" the recessive gene, which means s/he can pass it on to offspring.

So by that rule, if the female cat gets one O and one o (Oo), she should be orange, right?

Not with this gene.

With the O gene, the O and o actually combine their efforts, displaying both orange and non-orange, along with white. This is called a mosaic. This creates the true tricolor -- the calico or tortoiseshell. You must have the combination of the O and the o to create this, which means the cat must have two genes. Since only Xs can carry the O gene, the cat must have two X genes -- or in most cases, be a female.

Female patterns:

OO = orange cat
oo = non-orange cat
Oo = tricolored cat


Solid white cats are the result of a different gene that suppresses color completely. Young white cats often have vague smudges of color on the top of the head where the color is not completely suppressed. Sometimes this persists even in an older white cat.

So the cat will either be white, white with orange, or if it is a female it could be a tri-colour cat. Or it could be non orange depending on what recessive genes the 2 cats carry.

Answer 3

If the orange gene is dominant, the cat will be orange. If the white gene is dominant, the cat will be white. However, if the two genes are co-dominant, which means that they both will show up in an organism that carries them, the cat will be both orange and white.

Answer 4

The two alleles for this gene are actually orange and black, not white. In many cats, the gene for fur color is sex-linked, carried only on the X chromosome. This means that males will only have one copy of the gene, and females have two. Males are either black or orange, but females can have both alleles. A female with both alleles will have calico or tortoiseshell coloring (two words for the same thing).

Answer 5

The orange gene would be dominant, but that doesn't mean the cat won't be white or a combination of both.

Answer 6

is one gene dominate to the other. also you have to wonder how epistases will affect the color."gene hiding" also is one gene methylated there is a lot more to your question than two genes. If your wonder about epistases look and a calico cat" has different colors over it's body" hm mm you also have to wonder when differentiation occurs, is it in the first cell or a few cells after.

Answer 7

it depends on what gene is the dominant one in the cat

Answer 8

U mean allel i guess.
IF yes then it depends on which of those two is dominant.
Orange - orange clr
White - white clr
orange white if codominant - mix of those 2 clrs

Answer 9
