    I realize it's all semantics, but "regular pastels" ARE heterozygous pastels.
    I'm with you on this. I think that realizing that pastels and spiders are hets makes it much easier to predict offspring from complex crosses.

    Also, I'm not sure what the latest official notation is but I like the upper and lower case letters to show that there are two different "normal" genes involved in this cross; normal for pastel and normal for spider. I would write bumblebee X bumblebee as PpSs X PpSs with the P being the pastel mutant version and p the normal for pastel version and likewise S the spider mutant and s the normal for spider.

    I don't think this forum supports html tables but just in case this is how I would write the cross:


    <html><table border=2><tr><td></td><td>PS</td><td>Ps</td><td>pS</td><td>ps</td>
    </tr><tr><td>PS</td><td>PPSS</td><td>PPSs</td><td>PpSS</td><td>PpSs</td></tr>
    <tr><td>Ps</td><td>PPSs</td><td>PPss</td><td>PpSs</td><td>Ppss</td></tr><tr><td>
    pS</td><td>PpSS</td><td>PpSs</td><td>ppSS</td><td>ppSs</td></tr><tr><td>ps</td>
    <td>PpSs</td><td>Ppss</td><td>ppSs</td><td>ppss</td></tr></table></html>

    But I'm not at all sure any of the homozygous spider (SS) combos hatch.
