Indeed Baba Clarke...........

However.....

Is there another more diabolical reason to fear the hybrid?.?.?.?

One with biological origins?.?.?.?

Heterosis, hybrid vigor, or outbreeding enhancement, is the improved or increased function of any biological quality in a hybrid offspring. The adjective derived from heterosis is heterotic.

An offspring exhibits heterosis if its traits are enhanced (which is often defined in terms of evolutionary fitness) as a result of mixing the genetic contributions of its parents. These effects can be due to Mendelian or non-Mendelian inheritance.

    Is there hybrid vigour in humans?

    So, what happens when people from different human populations marry - is this likely to bring the benefits discussed above? Yes, it probably will, says Amos, both by reducing the number of gene-pairs that are broken and by increasing the number that are ‘both-good-but-different’. Combined, the result should be, on average, children who are genetically healthy, for example, who are less likely to catch ‘flu or who live a little bit longer. However, the size of this effect is extremely difficult to measure because so much of a human’s fate is due to the environment: having good genes won’t stop you getting run over by a drunken motorist!
