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:

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

In agranulocytes, what happens to the cytoplasm as the cell ages?

pishuonlain [190]

Answer:

As the cell ages the volume of cytoplasm increases, enzymes that synthesize DNA move from the nucleus to the cytoplasm, and there is a gradual build up of lipofuscin. While it is unclear how this directly affects the cell, it is known that once the DNA migrates from the nucleus it is unable to synthesizes enzymes.
