Two unlinked genes, A and B, encode very similar enzymes involved in the production of purple flower pigments in a particular plant species. Recessive, non-functional alleles a and b are available. If the A and B genes are functionall redundant, so a single functional copy of either gene is sufficient for purple pigmentation, what proportion of the progeny of a cross between AaBb double heterozygotes is expected to have white flowers?
