You are studying a population of
100 people and discover that 36
of these people are ss for a
genetic condition. use the hardy-
weinberg equation to figure out
the frequencies of the s and s
alleles. what are the frequencies
of the ss, ss, and ss genotypes?

The frequency of the s allele is 0.6, the frequency of the S allele is 0.4

SS frequency = 0.16 (16%)

Ss frequency = 0.48 (48%)

ss frequency = 0.36 (36%)

Explanation:

When there are two alleles of a gene in a population, the frequency of each allele = 1. That means that the sum of the frequencies of both alleles is 100%

p + q = 1

For our alleles, that means S + s = 1

For the 3 possible genotypes from 3 alleles,

p² + 2pq + q² = 1

For our genotypes, that means S² + 2 x S x s + s² = 1

Since we know that 36 people have the genotype ss, we can add that into our equation:

S² + 2 x S x s + 36 = 1

Therefore, to work out the value of s, we take the square root of 36 () = 6.

Therefore s = 6, which we convert to 0.6 (because we are talking about frequencies not percentages)

Back to our initial equation

p + q = 1, so S + s = 1

We know s = 0.6, so

S + 0.6 = 1,

so S = 0.4

For the genotype frequencies

p² + 2pq + q² = 1

0.4² + 2 x 0.4 x 0.6 + 0.6² =1

0.16 + 0.48 + 0.36 = 1

p² is the SS frequency = 0.16

2pq is Ss frequency = 0.48

q² is ss frequency = 0.36

foliated

[ explanation ]

foliation forms in a rock when pressure squeezes the rock together. the rock then has a design of many different color little lines. there are three types of foliated rock. the types are slate, schist, and gneiss. each type of foliated rock is different based on grain size and foliation characteristics. the lines appear when the rock has been under pressure.
