An autosomal recessive disease has an incidence of 1/10,000. What is the approximate frequency of heterozygote carriers for this
goblinko [34]

Answer:

Option B

Explanation:

Given

Number of incidences or frequency of an autosomal recessive disease = \frac{1}{10000}

As per Hardy Weinberg's equation, frequency of a recessive genotype is q^{2}

q = \sqrt{\frac{1}{10000} }\\ q = \frac{1}{100}

As per first equation of Hardy Weinberg's -

p+q=1

so ,

p = 1-q\\p = 1-\frac{1}{100}\\p = \frac{99}{100}

p^2 = (\frac{99}{100})^2\\p^2 =\frac{9801}{1000}

As per second equation of Hardy Weinberg's -

p^{2} + q^{2} + 2pq=1

Substituting the given values in above equation, we get -

\frac{9801}{10000} + \frac{1}{100} + 2pq=1\\2pq = 1-(\frac{9801}{10000} + \frac{1}{100})\\2pq = 0.99%\\OR[tex]2pq=1%

2pq = \frac{1}{100}

Hence, option B is correct.
