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

Eutrophication can cause excess algae growth. Which of the following describes how nutrients contribute to eutrophication?
dusya [7]

Eutrophication of water bodies like lake, pond, shallow stretches of river, etc. is the phenomenon where excess growth of vegetation on the surface of the water takes place. This excess growth results in the clouding of the water, depletion of dissolved oxygen in water, and the death of aquatic organisms. The primary reason for the cause of eutrophication is the presence of nutrients in excess amounts in the water. The nutrients B. come from fertilizer and sewage runoff.
