The Lederberg experiment that used the technique of replica plating showed that mutations _____ and are not a result of _____.
serg [7]

The Lederberg experiment that used the technique of replica plating showed that mutations are random and are not a result of the needs of the organism.

<h3 /><h3>What is a random mutation?</h3>

Random mutations are just that, they are changes in the genome of an organism that arise randomly. These mutations are the backbone of evolution and natural selection in that when they arise, if the organism becomes more adapted to survival as a result of this mutation, it increases its odds of survival through natural selection.

Therefore, we can confirm that The Lederberg experiment that used the technique of replica plating showed that mutations are random and are not a result of the needs of the organism.

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
