Dominant, codom, incomplete Dom???

Ok so I'm playin around with the genetics wizard and trying to figure out what to pair a pinstripe with. Anyway I paired pin x pin and got

75% pin
25% normal

Can someone explain this to me? I would have thought it would be all pins. I'm still a little fuzzy on the Dom, codom, incomplete Dom thing any help is appreciated thanks all.

On a side note I find it really funny that every time I spell codom my phone auto corrects it to condom. Hehe

Pinstripes are dominant, which means they do not have a super form, but they still only have to occupy 1 allele of the 2 (with the other being normal) to express the Pin morph.
So when you breed 2 Pins together each the mom and the dad have a 50% chance of passing the Pin allele.

Pin X Pin breeding odds are:
25% of neither the mom or dad passing their Pin allele
50% of the babies getting at least 1 Pin allele from either mom or dad
25% chance of both mom or dad passing their Pin allele which would result in offspring that have 2 pinstripe alleles, but since the Pinstripe morph is dominate it looks the same as if it only had 1 Pinstripe allele.

Lets say you did the same breeding with the Pastel gene, which is Co-Dom:
in Pastel X Pastel breeding odds are:
25% of neither the mom or dad passing their Pastel allele
50% of the babies getting at least 1 Pastel allele from either mom or dad
25% chance of both mom or dad passing their Pastel allele which would result in offspring that have 2 Pastel alleles, and since the Pinstripe morph is Co-Dominate it expresses the look of the Pastel Super form.

You take that 25% chance that would have been Supers and add it to the 50% of single allele animals.
Now for Pin X Pin 25% of the offspring would have 2 pin alleles making them better breeding stock, but since no super form expresses there is no way to tell which of the offspring got the 2 Pin alleles and who got just 1.

Make sense?

Ohhhh gotcha thank you!

just to add, in the snake world, we do not differentiate between co-dom and incomplete dom, we just call everything co-dom.

also if you breed pin x pin, the 2 allele pin they were talking about above, is called a homozygous pin. the advantage to this guy, is when bred, they produce 100% pin babies. you won't be able to tell visually if it is homozygous or not, but breeding can prove it out.

thats pretty funny about your phone, i know my friend's iphone always changes "most" to "molest"
