    Punnett Squares??
    Ok, so Im trying to figure out Punnett Squares.... I can do a pastel to a spider easy, but how in the world would you make one for a bumblebee to a pinstripe? Do you have to foil the first pair like you would a recessive trait or what??? How would I set up a square for a co-dom with 2 traits to a co-dom with only one trait???


    Heres what Im getting....Im lost

    NI=Pinstripe NpNs=Pastel Spider?
    Would it be.....

    ___N__ I
    Ns _____
    Np _____


    or

    ___N___ I
    NN ______
    Np_______
    Ns______
    sp ________
    That cant be right how would you combine them??? That would only give me 8 squares when I need 16 right?

    Or is it?

    ___N___ I___N____I
    N_______
    s _______
    N _______
    p _______

    Im only getting 4 norm 4pin 2 pastel 2 spider 2 spinner 2 blasts...but no Spinnerblasts or bumblebees... Which both should be in there??? I think.....
    Sorry I cant make squares on here so its hard to explain, Im just trying to figure out how to set up the square!

    Re: Sorry I posted this on the wrong page....
    We have a nifty little Tables feature that will help you format the punnet squares


    which would be coded like so:


    [TABLE="width=500px"] | 1 | 2 | 3 | 4
    1 | | | |
    2 | | | |
    3 | | | |
    4 | | | |
    [/TABLE]

    I know it has no relation to this thread, but I figured you, and others, would find it useful :)

    Hi,

    http://www.newenglandreptile.com/genetics_intro.html

    And to use the wizard you need to know the number of base morphs and how they are expressed. It's amazing once you have the basics but notsomuch when you are still learning those.

    Hi,

    Select 3 abnormal traits.

    Build query.

    In the boxes enter pastel (tick codominant ), spider (tick dominant ), pinstripe (tick dominant ).

    For a male bumblebee click het for spider and pastel in the male column.

    For a female pinstripe select het in the pin line of the female column.

    and click "wt" for the female in the spider and pastel lines and for the male in the pinstripe line.

    Then click ask the wizard.
