1% of sloths within a population show the recessive trait of a certain characteristic. This population is in HW Equilibrium. What is the value of p if p represents the dominant allele?
a)0.99
b)0.9
c)0.81
d)0.18
I know the answer is B, but why?
0.09
given q^2=.01 SHOW THE TRAIT
q=.1
p^2+2pq+q^2=1
p^2+.2p-.99=0
quadratic equation:
p=1/2 (-.2+-sqrt(.04+3.96))
p=1/2 (-.2+ 2 )=1.8/2=.9
check my math.
