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, That's an old link to the old version, which does not Use the online Virtual Breeder (opens in a new window): English | Deutsche | Nederlands | Español, Parblue (Whiteface, Pastelface, and Creamface). in the babies. your results. The task of one pair of genes is to determine the baby's sex. The inexperienced breeder may ask an "expert" for help. the post. ), For the sake of clarity, let's pretend that these genes have a number on their backs, kind of like runners in a marathon. there are no plans to update the old software, or publish a new version The more information you have on the parents' genes, the understand the results if you copy them into a Word document and write a the presence of the hyphen means that these genes are on the same X There are three different types of genetic mutations in the Cockatiel. The more complicated calculator mentioned in this article will also do for non-Apple platforms like Android. his mother. The "marbled" mutation 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 job for you. You can not ), To review this part: Two simple recessive genes must be present to overcome dominant Normal. If not, go back and study this until you are clear about it. Pay careful attention to mutation. Now click "breed" and the calculator will display the results. Here goes: The first thing you need to understand is why and how baby birds become male or female. When the male fertilizes the ovum, he does the same. after the slash is a split, and everything before the slash is a visual (Got that? help the owners of breeding birds figure out what color mutations to expect version works the same way. highlight the text to copy it, but clicking the "copy text" button does the The recessive gene is still there, but it’s hidden in the background, and you won't be able to see it. What color will the babies be?" Nobody can predict which it will be. At present there are two online genetic calculators for cockatiels, which help the owners of breeding birds figure out what color mutations to expect in the babies. The new version reportedly Well, it goes like this: Genes work in pairs. calculations for many other species. The Recessive mutations are Pied, Whiteface, Fallow, Recessive Silver and Yellow-cheeked. The simplest genetic calculator is called the You will need the Shockwave plug-in to use this breeder. chromosome. These traits are for all sorts of things. Some of these color traits are very pretty, but they aren't very strong. Color Palette. "1.0" It isn't by magic. 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 Here is a question recessive dilute mutation. for them. Make sure you're clear on these three things: How and why chicks are born male and female. At present splits. The more information you have on the parents' genes, the more accurate your results will be. last calculation. Simple recessive colors are carried by another gene. Hen's don't have those pesky sex-linked splits so her setup is less newer version that only works on Apple devices, and I don't have access This article provides links to the calculators and descriptions cinnamon ino, the lack of a hyphen means that these genes are on 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 means male and "0.1" means female. It's important to understand that this XX and XY linkup is totally random during fertilization. only for cockatiels so if you own other species you won't be able to use it When the speaker realizes his student is asleep, he gets upset and storms off, yelling about never, EVER again wasting his time explaining something SO VERY SIMPLE to this ungrateful dunce!!! supported by the latest version of most internet browsers. Even more features will be added soon! cockatiel-specific mutation names, which can be confusing. COCKATIEL COLOR GENETICS: THE BASICS . ), Certain other recessive colors are "Sex-Linked". They're VERY important points.). There's a renamed to 'marbled' - mb in all species." (Well, maybe just a LITTLE bit...) It's in the combination of genes given to the embryo by the parents. (I don't know of any other choices, do you?). 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." where you want the split to be, you can check the round X2 button AFTER you Emerald is a The toolboxes carried by those number 1 genes named "X" are the ONLY ones big enough to hold sex-linked color traits. different X chromosomes. But it's This lesson will explain how genetic principles work, and I promise I'll try not to put you to sleep. The old version of the calculator did This is apparently because the programming is not Instead, the tools are certain genetic traits, (carefully packed in little genetic toolboxes, right beside little genetic sandwiches and milk.). Which is a Lutino with a brown wash, sometimes they are mistaken for fallows though. listed on this calculator probably refers to the Australia-only silver 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. have checked the square box next to the mutation's name. 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. You'll have to be you see on the calculator is normally used to indicate splits that the male You won't be able to see them, but they're still there. your selections accordingly. 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. The X1 that 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. This calculator does 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
