If it says he's split to cinnamon-ino,
Half came from our fathers, the other half from our mothers. If they are two of the SAME trait, the male baby will BE that color, whatever it is. ------------------------------------------
In cockatiels a cross-over would be a Lutino Cinnamon. In a male chick, since they have two X's, both of the X's must be for the SAME sex-linked color in order for the color to be visible.
So the description fits reasonably well. sex-linked splits right if you're not familiar with the concept. If you want to do another calculation,

They're called "recessive" colors because they’re, genetically weak, when compared to the very strong, "dominant," Normal grey color trait. genetic characteristics is simple and straightforward. The genes named "Y" can't carry as heavy a toolbox, so Y's don't deal with sex-linked colors, and neither does any other gene. terminology which makes the results easy to understand. When the X's are pairing up, and are deciding if they're an XX or an XY combination, they also bring out any sex-linked recessive traits they might have brought along. If only one gene for a Recessive color trait is present, the recessive is hidden by the stronger Normal grey color. spangle mutation, but people in North America and elsewhere can use it

The Sex-linked mutations are Pearl, Cinnamon, Lutino, and Yellow-faced. Virtual Breeder Instructions. If it's an XY pair, the chick will be female.
This marathon, though, is a "Couples Only" marathon. These genes each have a purpose, and will decide EVERYTHING about the new baby, from its color, to its personality, and yes, even to its sex. GenCalc
If the pair happens to be XX, (a male chick,) the two X's compare any sex-linked trait they may have. (It could be any pair of genes, but let's say it's pair number one.) At present there are two online genetic calculators for cockatiels, which

If you read it enough, it'll make more sense. The parents have no control over which gene is being given, nor of what the outcome will be. (Not all the X's bring along this trait. You need to click "male", check the appropriate boxes for his genetic

Now click "female", choose her characteristics, and click "set female". When they found each other, during the big link-up, they discovered they had the same name, and it made their job real easy: They gave the baby their two names, and called him "XX."

I'll wait here...), In this particular marathon, let's pretend the job that gene pair number 1 has to do is name the sex of the chick. The Dominant mutations are Dominant Silver and Dominant Pastel-Face Typically there is a 3% chance of this occurring. This calculator uses more complicated terminology than the other one. A quick review: Sex-linked colors are carried with the X gene. If the breeder doesn't know what to pair with what, the results can be disappointing. and may or may not apply to the new Apple-only version. WARNING! But since she only has one X, HENS CANNOT BE SPLIT FOR A SEX-LINKED COLOR.

I know its heady stuff, but if you think about it, it’s not so bad. It takes two of any "simple recessive" gene to do the baby any VISUAL good. (Here's the big breakthrough:). characteristics, and then click "set male". If there was nothing saying that this chick should be a male, or that one a female, there would only be one sex, right? Ponder it awhile, then continue reading. If there is only one present, it won't have enough strength to out-do Normal. the calculator automatically assumes that it's on the X1. does consider crossovers, but since I have no access to it I don't know
As living things, we each have many gene pairs, inherited from our parents. In a female chick, (an XY,) only one sex-linked color gene is needed, since a female chick only has one X.

It doesn't really matter which parent gave him the gene, but
If you have a pair of birds who produce more female than male chicks, it’s only because the combined genes are more often XY than XX. you try to click the X2 button or X1 button without checking the square box
Ready? The sex-linked colors don't go away, though.

In order for these recessive colors to show themselves, they have to "double up" on the dominant Normal to overpower it. Return to the Cockatiel Color Palette.

is split to two or more sex-linked mutations. Normal is still stronger. This is the hinge upon which most genetic principles are based, and its importance cannot be overemphasized. When you stop and think about it, there must be SOMETHING that decides the sex of the baby. (Sound familiar?). If there is a slash sign "/" then everything
A bird will be Normal grey in its coloration unless a color-altering recessive trait is present. X is the only one who can. Unfortunately, this scenario happens all too frequently, and it is a shame.
It can be a challenge to get the
