I think telegony is absolutely real. Beyond one dude's semen influencing the next dude's sired offspring, I think even our learned behaviors can influence the genetic imprinted code; perhaps it's even by way of the blood. To comprehend the last part, think about phobias you cannot explain; almost to a point of knowing, or feelings that validate the phobia.
Sure I could be wrong, but look at modern science influencing our genetics by way of extra dna in vaccines, and other means. Why do they do this? Sure, they've got their 'doctorate' level mumbo jumbo, but think about this, modern medicine is considered 'mainstream'; while traditional remedies that have been around for thousands of years, is considered 'alternative'.
Money, and lobbying made that simple switch, just in the last 100 years or so. Strange, no?
