    Going Crazy on Genetics Please Help!

    Ok so I’ve drawn about 600 punnett squares and I just can’t figure this out.

    I'll give a couple scenarios someone please draws it out before I go crazy it’s much appreciated.

    Albino spider ball python

    Guy says he made then from 100% het albino spider x 100% het albino

    Can you draw a punnett for that? And how would you get a 100% het albino spider

    Is that a spider x albino

    I can’t figure this out. That just one morph I can’t figure out how it works and I’m usually very quick with punnett square. Anyone please help.

    Thanks
    Tony

    Spider is dominate so there is a 50% chance that an animal will be spider. With 2 het Albino animals there's a 25% chance of albinos. From the pairing 100% het albino spider x 100% het albino you would have a chance at: Normal, spider, albino, and spider albino offspring, or just spider and spider albino offspring if the snake is homo for spider.

    A punnet square really doesn't help with codom and dominate genetics. Spider x albino would make a clutch of het. Albinos with all or about 50% of them being spider based on if the snake carried one or two genes for the spider trait.

    How would you even get a 100% het albino spider?

    Only way I can think of to get 100% het albino spider is to breed albino spider x 100 het albino spider. How do you get a albino spider without the 100% het?

    Lots of ways, Albino x spider, Albino spider x normal, Albino spider x anything ; will all give you 100% het for albino with 50 or 100% offspring of spiders.

    Albino x Albino spider will result in 100% albino offspring the spider trait will matter on how if the animal carries one or two of the traits genes on an allee.

    Spider is dominate (this gene is more powerful than the normal gene), this meaning it's the same if you have a allee showing Ss or SS. Any animal showing the allee as Ss (carring one gene) will produce 50% spider offspring, animals with a allee of SS (carring two genes) will produce 100% spider offsping.

    This differs from co-dominate (this gene is of a equal power to the normal gene resulting in a diffrent morph when only one gene is on the allee) traits like pastel where Pp is a pastel and PP is a super pastel.

    Recessive genes (this gene is weaker then the normal gene resulting in normal looking offspring when only one gene is on the allee) the animal needs to carry two genes on the alle for the morp to be seen ie. AA

    So the only way to get an albino spider python would be to breed an albino x spider. Get a 100% het albino spider and x that to 100% het albino?

    No, not the only way. You could breed an het albino spider to a albino or het albino or a albino spider to an albino or het albino. The important part is that both parents have the albino gene and at least one carries the spider gene.

    Then why can't you get an albino spider from albino x spider? Do both partners have to carry the recessive?

    Yes, both parents would have to be carriers of a recessive gene for the chance of it showing as a morph in the offspring.

    If only one parent carries the gene a part of the offspring would be gene carriers but because the gene is recessive to the normal gene they would not show any affects of having it though they could pass it on to their offspring.

    It's a bit more complicated in corn snakes where ultra is co-dominate to amel but both are recessive to the normal gene.
