    HI There!

    That is a god question. (as usual)

    This is an an example where there is a blending of traits. Instead of Red being dominant when it mixes with Blue in the genotype Rb (or RB) you get purple! This is an example of incomplete dominance. In this case there really isn't one allele that is dominant.

    One note, if this were co-dominance you would see red and blue spots! :-)

    Have a good night!

    Mr. Forde :-)

    Hi Mr. Forde,
    I was going to talk to you at school today, but you weren't there, so I will ask you it now. I am going to be absent tomorrow(Fri.) to go to yale Hospital for a inpatient study. I was wondering if there is any homework or work that I would miss that you could possibly give to Maybe Lindsay Green or Janay Parott. Thanks.
