<span>The answer is A. p2 = 0.36, 2pq = 0.48, q2 = 0.16.</span>

Let's first distinguish alleles frequencies from
genotypes frequencies:
p - a frequency of R allele,
q - a frequency of r allele,
p² - a frequency of RR genotype,
2pq - a frequency of Rr genotype,
q² - a frequency of rr genotype.</span>
<span>
<span>The gene frequency of allele r changes from 0.38
to 0.40, thus:
q = 0.40</span>
Now, we will implement this in the following
equation:
p + q = 1
If q = 0.40, then:
p + 0.40 = 1
</span>⇒ p = 1 - 0.40<span>
</span>⇒ p = 0.60
<span>
<span>Now, the frequencies of both alleles are know
and it is easy to calculate the genotype frequencies:
- the frequency of RR genotype: p² = 0.60² = 0.36</span>
- the frequency of Rr genotype: 2pq =
2 · 0.60 · 0.40 = 0.48
- the frequency of rr genotype: q² = 0.40² =
0.16</span>
<span>
<span>Therefore, the new genotype frequencies in
that population are p2 = 0.36, 2pq = 0.48, q2 = 0.16.</span></span>
I think Metamorphism changes only the shape of rocks. I'm not a 100% sure but correct me if I wrong
<span>Hypertension is another term for high blood pressure. This occurs when there is too much pressure put on the blood vessels. The heart gets affected because it is pumping against the pressure, which causes strain on the heart. This can cause thickening of the heart walls, which can lead to other heart problems.
Stroke occurs when there blood supply to the brain is reduced or obstructed. This deprives the brain of oxygen and other nutrients. The occurrence of stroke increases with blood pressure because there is persistent pressure on the vessels which can ultimately lead to stroke. </span>
Answer:
In sonographic measurements performed in the transverse view, the diameter of aorta (Ao) constituted 15.7 mm, the longer dimension of the inferior vena cava (IVC1) equaled 28.4 mm and the shorter one (IVC2) – 15.5 mm. In the longitudinal view, Ao equaled 15.3 mm and IVC – 18.8 mm (tab.
Answer:
Wheezing happens when the airways are tightened, blocked, or inflamed, making a person's breathing sound like whistling or squeaking. Common causes include a cold, asthma, allergies, or more serious conditions, such as chronic obstructive pulmonary disease (COPD).
