This sample contains 1480 fans in total.
a. Is the population at Hardy-Weinberg equilibrium
with respect to either or both of the Q and
R genes?
b. After one generation of random mating within this
group, what fraction of the next generation of football fans will be QF
QF
(independent of their R
genotype)?
c. After one generation of random mating, what fraction of the next generation of football fans will be
RCRC (independent of their Q genotype)?
d. What is the chance that the first child of a QF
