    miss i have a question if IA IA is blood group A,why did you say in the genotype of the man is IA i because i is recessive when it is said in the question that he is blood group A?

    Morning ma'am I am having trouble to understand the co-dominace example problem
    Since all the offspring are heterozygous
    Which means they are different alleles why is it that the letter "W" was not represented with a lower case "w" however it was represented with a capital letter "W"

      Hi Valeria.
      Remember that this is a co-dominance example. This means that both alleles are equally dominant and that if they are heterozygous (RW) both are equally dominant and therefore we do not write them in lower cases. Only with complete dominance will you have one allele that is dominant (written with a capital letter) and one that is recessive in a lower case. I hope this helps. Ask me if you need further explanation.

    If white flower became hereditary and red also became hereditary what will be the phenotype and percentage

    For incomplete dominate why didn't we say WR WR why start with R

    Why is it RW and not WR

      Hi, you can write it as WR as well. They will still mark it correctly as WR will still provide the same offspring as RW. Generally I tell my learners to write the allele first that is mentioned first. So if they mention Red first then R will be written before white. Also just because R comes before W in the alphabet my brain writes it first😉. But once again they will still mark it correct if you switch the two.
