October 1, 2014: My mother is A blood group, my father is O blood group and I'm O blood group.  I thought that my mother’s A blood group would always dominate my father’s O blood group, so I would have to be an A blood group.  Could you let me know if this is the case please?

August 19, 2014: I read on your site that a recessive trait is often the result of a broken gene.  I can’t seem to figure out why a broken gene would lead to the green peas in Mendel’s famous experiment.  Do they know why yellow is dominant over green?

March 27, 2013: In people with one dominant and one recessive gene, does the recessive gene not make anything?  If so, does the dominant gene stop the recessive gene from making anything?  Or, does the recessive gene make a broken protein?  If the recessive gene makes something, shouldn’t it be incompletely dominant or co-dominant?
