PLEASE HELP ASAP
Would really appreciate it but would understand if nobody replies.
Thanks in advance.

1.

Frequency of dominant allele = p=0.5196

Frequency of recessive allele= q=0.4804

% homozygote dominant= p^2=27%

% homozygote recessive= q^2=23%

% heterozygotes = 2pq= 50%

2.

p=0.7

q= 0.3

p^2=49%

q^2=9%

2pq= 42%

3.

p=0.409

q= 0.591

p^2=16.7%

q^2= 35%

2pq= 48.3%

4.

p=0.99

q= 0.01

p^2=98.01%

q^2=  0.01%

2pq= 1.98%

Explanation:

1. The percentage of homozygous dominant organism is expressed as p^2 and its value in this question is 27%. Using the information, we can find the frequency of the dominant allele (p)

p^2= 0.27

p= √0.27= 0.5196

After we get dominant allele frequency we can find recessive allele frequency

p+q=1

q= 1- 0.5196

q= 0.4804

With recessive allele frequency and dominant allele frequency, we can find the heterozygote and homozygote recessive.

homozygote recessive= q^2= (0.4804)^2= 0.2307= 23%

heterozygote =  2pq= 2(0.4804)(0.5196)=0.499= 50%

2.

Only an organism with homozygote recessive genotype will show symptoms and signs of sickle-cell disease, so 9% is the percentage of q^2.

q^2= 0.09

q= √0.09= 0.3

p+q=1

p=1-q

p=1-0.3= 0.7

p^2= (0.7)^2= 0.49= 49%

2pq= 2(0.7)(0.3)= 0.42 = 42%

3.

The 35% population of the moth is homozygote recessive (q^2). We can use the same step as problem 2 then

q^2= 0.35

q=√0.35= 0.591

p+q=1

p=1-q

p=1-0.591=  0.409

p^2= (0.409)^2=0.1672= 16.7%

2pq= 2(0.409)(0.591)= 0.4834 = 48.3%

p=0.409

q= 0.591

p2=16.7%

q2= 35%

2pq= 48.3%

4.

Cystic fibrosis is a homozygous recessive disease with a population rate of 1/10,000. That means the percentage of the population with q^2 gene will be: 1/10000= 0.01%

Then, the rest will use same step as question 2

q^2= 0.0001

q=√0.0001= 0.01

p+q=1

p=1-q

p=1-0.01=  0.99

p^2= (0.99)^2=0.9801= 98.01%

2pq= 2(0.99)(0.01)= 0.0198 = 1.98%

i dont know this but ask your teacher for !

answers are:

lysogenic     viral dna merges with host cell dna

lysogenic     no symptoms

lytic               viral dna takes over

lysogenic     virus does not destroy host cell

lytic               virus destroys host cell

lytic               induces symptoms of viral infection

lysogenic       cell reproduces and spreads provirus
