approximately eight according to cent of fellows are colour
blind, a price that is sixteen times better than it is in ladies. The gene that
allows us to peer shade - particularly crimson and green - is on the X

faulty color gene on that unmarried chromosome. girls have X chromosomes, so a non-faulty gene on one
chromosome can balance out a faulty gene on the opposite.
"however guys inherit shade blindness from their
mother," says Dr Michael Steiner, a past president of the Royal Australian
and New Zealand
university of Ophthalmologists.

most not unusual eye issues - cataracts, glaucoma, macular degeneration and
diabetic eye sickness - have an effect on each sexes similarly.
