... F) One baby in 10,000 in the US is born with PKU, which until very recently was a recessive lethal condition. Does it seem likely that the population is in equilibrium with mutation balanced by selection? (Explain) This would mean a mutation rate of 1 in 10,000 which seems a bit high; there may have ...
