What do you get when you breed a normal with a ????

[chapskis1]

I don't understand genetics at all. I don't get what happens when you breed a dominant with a co-dominant etc.

Right now I have a normal male. I'm thinking about getting an albino female. If I breed the two, do I get half normal and half albino? Can someone explain it to me, or point me to link?

Thanks,

George

Albinos are recessive, so if you bred your normal to an Albino, you'd only get 100% het Albinos that all look normal.

Well for one albino is a recessive trait therefore if you breed a female albino to a male normal all you will get is normal looking snakes that are heterozygous for albino. Unless of course the male is a het albino. Then you would get .50 normals het and .50 bino's.

Codominant genes have a super form meaning when bred to the same morph example: PastelXPastel you get a super pastel.

Dominant genes are only made if you have one to reproduce. Such as a Pinstripe. There is no super form and it is only reproducable if you have one in your collection to breed it to something.

Hope that helps a bit

Ha Ha Heather you beat me to the punch! LOL

[chapskis1]

So, you get an albino by breeding two 100% het albinos? Because it is a recessive gene? If you have a dominant trait, then you get 50/50 if you breed a dominant with a normal?

How do you know which genes are recessive, and which are dominant?

What do you get if you breed two of the same recessives (ie two albinos) -- and do you get all dominants if you breed two dominants together? (ie two pinstripes = all pinstripes?)

Use the stickys in morphs threads. They will give you the basic co-doms/doms and reccesive genes. Good tool to start with.

Ok, let me see if I can make this more clear.

Blue eyes are a recessive trait in humans. Children receive half their genes from their mother, and half from their father. In order to determine eye color, you need to look at the eye color gene that came from the mother, and the eye color gene that came from the father.

If both parents have blue eyes, then the only genes they have to give are blue-eye genes--their child will have blue eyes. When we can see the result of the gene's presence by looking (or by symptoms or other features) we say the gene is expressed. So, the blue eye gene is expressed when two copies of it are present in the child.

Now, brown eyes is dominant. If someone has one brown-eye gene, and one blue-eye gene, their eyes will be brown.

If both parents have brown eyes, but carry the blue-eye gene, then their child has about a 25% chance of having blue eyes--it will only happen if they get the blue-eye gene from their father, AND the blue-eye gene from their mother. Anything else, and they have brown eyes. (They also have a 25% chance of not getting the blue-eye gene at all, and thus not being able to produce any offspring with blue eyes down the road, because they will have no blue-eye gene to contribute).

It's exactly the same with recessive genes in snakes. Albino is a recessive gene. Both parents must have the albino gene to contribute in order to make an albino offspring. If they have only one copy of they albino gene, they will look normal, and then there is only a chance that they'll have albino offspring.

If you breed two het albino snakes together -- that is, two normal-looking snakes that have the albino gene--then about 25% of their offspring will be albinos. Another 25% of their offspring will be normal and will NOT carry the albino gene.

Since you cannot tell a normal snake apart from a het snake by looking at them, the remaining 75% of the clutch will be called "66% possible het albinos". Those are approximately the odds that any individual snake will actually be carrying the albino gene--you will not know if they carry it or not until you breed them to another snake that carries it.

Co-dominant is easy. Co-dominant is just like recessive, except that you CAN tell by looking at the animal whether or not it carries the single gene. A lesser platinum is actually 'het for blue-eyed leucistic'. Heredity works just the way it does with recessive genes. A lesser platinum has 1 lesser platinum gene to contribute, and 1 normal gene to contribute. If you pair it with a normal snake, half of them will inherit the lesser platinum gene, and half will inherit the normal gene. Since the normal snake has only normal genes to contribute, that means half of the offspring will be normal, and half will be lesser platinum (het for BEL). You can think of co-dominant as 'half-expressing' the mutant gene--the animal looks different, but it doesn't look the same as an animal with 2 copies of the gene.

Now, for dominant traits. Dominant traits override the normal gene, and are expressed fully even if only one copy of the gene is present. So, a pinstripe snake, when bred to a normal snake, will pass on a pinstripe gene about half the time, and a normal gene about half the time--thus, half the offspring will be pinstripes. We know that pinstripe is dominant because if you breed 2 pinstripes together, 25% of the offspring will be pinstripes that look just like every other pinstripe, but have 2 copies of the pinstripe gene. These super-pinstripes will always produce all pinstriped babies if they are bred to a normal, because they only have pinstripe genes to contribute, and no normal gene to contribute--so all offspring will always have one copy of the pinstripe gene.

I hope this helped.

try this site out. i like to go on there and just play around. if u want one to be a normal dont click anything in one of the boxes and that will be normal

By far the best genetic link provided so far. Thanks a bunch. Saved as a Fav now.
