Hi Alea.....
"A single gene disorder is the result of a single mutated gene. Over 4000 human diseases are caused by single gene defects"
Primates i read,have about 400 single genetic disorders......hence
the multiple of 10.
For instance the Primate's immune system has a response
for cancer,whereas we do not.....where in the evolution chain
did we lose this immune response & why do we suffer from
cancer still today after millions of years of evolving....why did
evolution decide it would be a good idea to take away our
ability to respond to cancer..........?
How did the RH negative factor ever survive in the
chain of evolution?
