Suppose a population is carrying a condition controlled by two alleles: R (dominant) and r (recessive). Only homozygous individu
White raven [17]

<span><u>The answer is A. 72.25 percent.</u>

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>r</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>R</em> allele frequency (<em>p</em>), the formula p + q = 1 is 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>R</em> allele (<em>p</em>), it is easy to determine the frequency of the RR genotype (p²):
p² = 0.85² = 0.7225

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

Sculptural materials that are soft, pliable, and are easily manipulated possess what specific property
iren [92.7K]
Subtractive process is used to form sculpture is by removing material from a block or mass of wood, stone, or any other material. This is usually done with sharpened tools.
Carving is one of the oldest sculptural techniques. Whereas, casting, modeling, and assembling are the other three techniques. 

Sculptural materials that are soft, pliable, and are easily manipulated possess ephemeral property. Examples of such materials are plaster of Paris, wax, unfired clay, and plasticine<span>.</span>

If the conservative model had been correct, how many generations of bacterial cell division would have had to pass before mesels
Reil [10]

No generations or hybrid would form before meselson and stahl would have observed evidence of a band in the cscl gradient.

The conservative model predicts that, following a single replication, half of the newly formed DNA double helices will be made entirely of the original, or old, DNA, and the other half will be entirely new. Then, each double helix would be completely replicated during the second round of replication. After that, 25% of the double helices would be all new, and 25% would be entirely old. Thus, the fraction of entirely new DNA double helices would increase with each succeeding round of replication, but the total number of completely unique DNA double helices would remain constant. Therefore, no hybrid DNA molecule containing 14N and 15N is replicated in the conservative model.
