Little help please?

[Tidus10]

So I have a pastel YB male and a female pastel and female normal.. I'm thinking if I throw him to the pastel I will get
33%% super pastel
33% super pastel YB
33% pastel YB
right???

And if he goes to the normal I would get
50% pastel
50% YB

Just want to know if I'm thinking of this right

Hi,

Sadly not.

Running it through the genetics calculator here we get;


And with the normal female;


Nice calculator by the way.

How do you get a normal? The female pastel has one normal gene and the pastel YB has no normal gene but you can still get a normal?

Hi,

Pastel is a het form so there is a normal gene there and yellowbelly is also het so there is a normal there.

If there were no normal genes then it would be a superpastel ivory not a pastel yellowbelly.

The male Yellowbelly Pastel is not a homozygous form. Its basically a double het for ivory and super pastel, if you look at it that way, and has a "normal" gene still.The only way to get no normals is to breed a homozygous to something, such as if your male was an Ivory Pastel OR Super Patel Yellowbelly. Hope that makes sense, lol.

* haha, Dr Del, you're fast!

So for the pastel YB it has a normal gene and pastel and yellowbelly gene? But the normal isn't showing 0_o

I think I've confused myself..

Hi,

Yes - you need to understand the differences between what we call recessive, co-dom and dominant morphs.

A recessive looks normal as a heterozygous but visualy different as a homozygous.

A codom looks different (from a normal) as a heterozygous and different again ( from both normal and the het ) as a homozygous.

A dominant morph looks different (from a normal ) as a het but then looks the same as a het when it is homozygous.

Pastel and yellowbelly are the het forms of their respective mutations - the homozygous forms (which are the ones that cannot produce normals ) being superpastel and ivory.

It tales a little getting used to but once it gets sorted out into which morph is in which group things get a lot easier to predict.

Think of the genes as being in pairs if it helps.

Pastel = one pastel gene and one normal gene.
Superpastel = two pastel genes.
Yellowbelly = one yellowbelly and one normal gene.
Ivory = two yellowbelly genes.
