The answer is 9%.

To calculate this we will use some <span>formulas of the Hardy-Weinberg principle:
</span><span>p² + 2pq + q² = 1 and <span>p + q = 1
where:
</span></span>

<span>p - the frequency of the A allele.
q - the frequency of the a allele.</span>

p² - the frequency of dominant homozygote (with AA genotype)

2pq - the frequency of heterozygote (with Aa genotype)

<span>q² - the frequency of recessive homozygote (with aa genotype)</span>

<span>We know:</span>

p = 70% = 70/100 = 0.7

q = 30% = 30/100 = 0.3

We need to calculate the frequency of the genotype aa:

q² = ?

Since we know the frequency of allele q, it is easy to calculate the frequency of the genotype aa:

q² = 0.3² = 0.09 = 0.09 · 100% = 9%

Mark turned quickly, pivoting on his right foot, while he was playing basketball. He felt a sudden, sharp pain in his knee and f
Contact [7]
<span>The correct answer is that he has injured one of the tendons or ligaments that help keep his knee in place, connecting it to the surrounding muscle and bone. As a result of this injury, his knee is no longer connected to the muscle and bone, thus it wobbled sideways when he started walking. He needs to go to a doctor immediately who can fix his knee so as to prevent further complications - he just needs his knee to be set in place again.</span>

Because all of these<span>tests would help me to determine if drugs were to be present in the crime scene</span>3.It's important forscientist to have as much information as possible about the place that the drugsubstance is found because many factors can contribute when identifying a type ofdrug and because there might of have been some other substances with the drugand this could affect identifying the drug substance
