One of the most important precautionary measure to be taken when working with explosive chemicals in the laboratory is the use of safety goggles. However, in this case, Maria claimed that she could not see through the safety goggles and wore them on top of her head rather than over her eyes.

Maria accidentally splashed some chemicals into her eyes while trying to pour it into a beaker. The primary or initial response to this happening is to immediately FLUSH OR RINSE her eyes with water. This will flush away the chemical from her eyes before it can have its detrimental effect.

Assume that all possible “ABO” blood phenotypes are present in a human population that is in Hardy-Weinberg equilibrium. If the

SOVA2 [1]

Answer:

the frequency of individuals with Type B blood in the population is 0.1977

Explanation:

Given:

Frequency of A allele is p = 0.24

Frequency of the individuals with blood type O is r = 0.38

Question: What is the frequency of individuals with Type B blood in the population, fB = ?

You need to apply the Hardy-Weinberg Equilibrium:

p²+q²+r²+2pq+2pr+2qr = 1

Here,

p, q and r are the frequencies of the alleles

Calculating the frequency of the allele q:

$r=\sqrt{0.38} =0.6164$

q = 1-p-r = 1-0.24-0.6164 = 0.1436

Frequency of individuals with type B blood:

$f_{B} =q^{2} +2qr=(0.1436)^{2} +(2*0.1436*0.6164)=0.1977$
