help me on carrier advantage/evolved via sexual selection Posted
12 December 2012 - 08:47 AM Given the potential advantage to
carriers, discuss how this advantage might have evolved via a
sexual selection (SS) mechanism. Be sure to define SS, put it in
the context of natural selection (NS), and clearly state what
the advantage to carriers is. Remember that evolution by NS
takes place in the context of specific environments so be sure
to include the role of the environment. Posted 12 December 2012

noted the people with sickle cell have a protective mechanism
against malaria that means that they are less likely to get the
disease, and hence have a better chance of surviving and/or have
a shorter disease course meaning (in the absence of modern
technology/shops etc.) that they are more likely to survive to
hunt for food again. Note the incomplete recessiveness - partial
expression of the recessive gene is enough to confer malaria
resistance... there's
