Dominat gene Questions

I am led to believe that if you were to breed say a Spider x Spider you get 100% spider. Also Spider x Normal = 100% Spider

Yet in the sticky the example given for dominant genes is that spider x normal would be 50/50. But in the links he gave below say spider x normal is 100% spider.

Is there a link to how the different genes interact like dominant x recessive? Like how you would get albino spiders? The Genetics Wizard website is confusing as heck when it comes to dom/co-dom genes.

Here's the main genetics page...

I love this site to look at the combo's.

Exactly my point. I had already been to this link and it says spider x normal is all spiders.

They big ol' stcky thread says different. It says spider x normal is 50/50. You know the one with the colorful pics of DNA and little arrows.

Did I miss something?

Yes...the heterozygous Spider x Normal is 50/50...the Homozygous Spider x Normal is all Spiders...

You will NOT get all spiders from a normal x spider. You have the chance of that or a chance to all normals.

Last year i got 6 eggs 4 spiders 2 normals.

lol! Ok I see as usuall no matter what you do genetics are hit and miss. But hey to breed a spider to a het for zilch normal and get any spiders is better than nothing.

Isn't it the same way for spider x spider, 50/50? I thought Dom was allways 50/50.

See! So many raved on how helpful that sticky was but it seems like I wasnt the only one who didnt completely understand it.
