There are 3 possible genotypes: NN, MN, or MM. In a group of 500 people, the frequency of genotype NN is 40%. How many individua
Readme [11.4K]

235 are the Individual numbers that would expect to have the MN type of genotype.

There are two equations necessary according to Hardy-Weinberg Equilibrium:-

<em>p</em> + q = 1

p² + 2pq + q² = 1

Let,

NN= p

NM=2pq

MM=q

So, according to the question, the frequency of genotype NN is 40%

40% of 500 = \frac{500*40}{100} = 200 Numbers of individuals

Frequency of individuals <em>p </em>= \frac{Numbers of individuals}{Total populations} = \frac{200}{400} = 0.4

Find <em>p</em>² by taking the square root of <em>p</em>.

√(<em>p</em>) = √(0.4)

= 0.632

So, <em>pp + qq = 1  </em>

<em>qq</em> = 1 - <em>pp </em>=  1 - 0.63

q = 0.37

The allele frequencies in the population are known, now finding the frequency of heterozygous genotype.

By Multiplying<em> 2 × p ×q  </em>to get heterozygous genotype

<em>2pq =  2 × 0.63 × 0.37` = 0.47</em>

<em>2pq = 0.47</em>

<em>So, 2pq × total population = 0.47 × 500 = 235, NM genotype.</em>

What industry is the primary user of perchloroethylene, a chemical that researchers at Boston University have linked to mental i
Fofino [41]

The dry cleaning industry is the primary user of the chemical perchloroethylene (PCE). The research done by the researchers at the Boston university have found that the PCE chemical increases the risk of developing mental illnesses in the people working with it. Since, it is a common name in the dry-cleaning industry, the workers in this industry are much more prone to mental illnesses a compared to other people.

Hence, the answer is 'dry cleaning industry'.
