Answer:
Subduction zones are important for several reasons: ...

Explanation:
<span>The ability to taste PTC is due to the presence of at least one dominant allele for the PTC taste gene, so a nontaster genotype should be homozygous recessive(pp). If the frequency of pp is 45%, then frequency of p would be:
pp=0.45
p= </span>√0.45
p=67%
p+P= 100%
P= 100%- p
P= 100%-67%= 33%
<span>The number of North American population that has is homozygous dominant(PP) genotype would be:
P=33%
PP= 33%^2= 10.89% = 0.1089 = 0.11</span>
