Where the gators are
Alright im getting so confused with the genetics stuff.

If i paired a male norm with a female spider what whould i get?

100% Het Spider
or
50% Norm 50% Spider

Do dominate genes mean if bred with a norm ull get half and half and codoms only hets?
 
i think i got it

Spider is Bb
Norm is BB
B B
B BB BB

b Bb Bb

so 50/50

Since the spider is a dom

What would a codom look like?
bb?
 
I would think you would end up only with hets for spider.
 
wait one more if anyone can help me out cause i might be getting a het pied male. sorry for all the questions

het pied male X norm female?

Is the only way to get a pied by mixing 2 hets together?
 
i found this chart. Is ths wrong then?

You have "codominant" confused with "recessive". Codominant means that there are two dominant traits that can both be expressed at the same time (human blood type is a good example if you know anything about that). Recessive means that it is only expressed if dominant allele for that trait is there to overshadow it.

The way that chart shows it, the spider female is heterozygous dominant for the trait (meaning she has one allele for the spider trait and one for normal). In that case, 50% of the offspring will be spider, 50% normal. On the other hand, if she were homozygous dominant for spider, 100% of her offspring would also be spiders
 
At any rate the idea is not to breed normals with other morphs unless there is a market. I know there are markets for spiders, pastels, bumblebees, etc, but standard balls wholesale for, what, $5?
