Joe,
I know of the paper....I haven't read it in a long while, But....
I do not believe his work can be re-created with captive bred melanistic thayeri. At least with the ones we are left with in this day and age. I do not believe it is a simple recessive trait (anymore?) since a melanistic X melanistic pairing does not produce all melanistic offspring as a recessive Mendelian trait should.
Is our gene pool tainted in a way to make the trait 'weaker' than it once was?
I am no gene-ologosit, but I do know something is 'different' than when Osborne did his work some 25 years ago.
