Refsum Disease question. Use the following information to answer the next 2 questions

#1. Use the following information to answer the next two questions.

Refsum Disease
Refsum disease is a genetic disorder that is inherited in an autosomal recessive pattern. Individuals with adult Refsum disease do not have the enzyme to breakdown phytanic acid. As a result, phytanic acid accumulates in the brain, blood, and body tissues. As the disease progresses, individuals with Refsum disease experience loss of vision, hearing, and sense of smell, as well as balance and coordination problems.

In a population, the frequency of the recessive allele for Refsum disease is 0.35. What is the expected frequency of the carriers in this population?

To answer this, I'll need to know does 0.35 represent 0.35% or 35%.

Confused a little.

i think it is 35%
this is how i did this question
frequency=number in subgroup/total number = 100%-35%

= 65% or 0.65
not sure if this is even right or not. sorry for the late reply, i just logged on

i followed an example that my teacher had in her notes
