Lucy I have done a bit more reading today and this article:
http://bulbnrose.x10.mx/Heredi... was an eyeopener to me, teaching me that there are indeed dominant white genes in iris, which are different than their recessive white genes. Very interesting. Thanks for tipping me off to this. Mendel would have been surprised, because his white-flowering strain of pea flowers was always recessive. So is white in soybean flowers, violets, and others.
