Suppose a population is carrying a condition controlled by two alleles: P (dominant) and p (recessive). Only homozygous individu

als that have two copies of the recessive allele have the condition. If the p allele is found in 15 percent of the population, what's the frequency of the PP genotype?
A. 25.5 percent
B. 72.25 percent
C. 2.25 percent
D. 12.75 percent

<span>The answer is B. 72.25 percent.

The Hardy-Weinberg principle can be used:</span>

<em>p² + 2pq + q² = 1 </em>and <em>p + q = 1</em>

where <em>p</em> and <em>q</em> are the frequencies of the alleles, and <em>p²</em>, <em>q²</em> and <em>2pq</em> are the frequencies of the genotypes.

<span>The <em>p</em> allele (<em>q</em>) is found in 15% of the population:
q = 15% = 15/100
Thus, q = </span><span>0.15

To calculate the <em>P</em> allele frequency (<em>p</em>), the formula <em>p + q = 1</em> can be used:
If p + q = 1, then p = 1 - q
p = 1 - 0.15
Thus, </span><span>p = 0.85

Knowing the frequency of the <em>P</em> allele (<em>p</em>), it is easy to determine the frequency of the <em>PP </em>genotype (<em>p²</em>):
p² = 0.85² = 0.7225

Expressed in percentage, p² = 72.25%.</span>

Which of the following will lower blood pressure? Which of the following will lower blood pressure? angiotensin II atrial natriu
garik1379 [7]

Answer:

Angiotensin II atrial natriuretic peptide(ANP) lowers blood pressure.

Explanation:

Increase in plasma volume leads to increase in blood pressure and a decrease in plasma level also leads to a decrease in the blood pressure. ANP is an enzyme which stimulates the decrease in blood levels through certain factors thereby causing a decrease in the blood pressure.

Meanwhile ADH stimulates increase in blood plasma levels thereby increasing the blood pressure.

Ants carrying leaves may indicate their food habit is an eater of plants or
SIZIF [17.4K]

Most ants are omnivores and are okay with eating plants, seeds, nectar, and even animals. Ants are also opportunistic in their feeding habits, which mean that they can easily adapt to the environment and will eat what they can to remain alive
