In a particular species of frogs, black spots are a dominant trait and their absence is a recessive trait. In a population of fr
kipiarov [429]

The expression which is the correct way to calculate the frequency of the dominant allele is 134/200. Thus, the correct option is D.

<h3>What is Allelic frequency?</h3>

The allelic frequency may be defined as the sum total of all the alleles of a gene in a population. It represents the overall genetic diversity within a population.

The allelic frequency is calculated by the formula when the genotypes are given in number. It is as follows:

2 × Number of Purebred dominant + Number of heterozygous/ 2× Total number of individuals in a population.

∴ Allelic frequency of dominant allele = 2 × 50 + 34/ 2× 100 = 134/200 = 0.67.

The allelic frequency of the Dominant allele is 0.67 while the allelic frequency of the recessive allele is 0.33.

Therefore, it is well described above.

Two students decide to repeat the Hershey and Chase experiment with modifications. They decide to label the nitrogen of the DNA,
Ipatiy [6.2K]

Answer:

radioactivity will not be able to tell the difference between the DNA and proteins

Explanation:

It seems that the experiment will fail to show what Hershey and Chase showed because they modify some of the aspects. These modifications will cause changes to the results, the main one being that radioactivity will not be able to tell the difference between the DNA and proteins. This is because Amino Acids are proteins that also contain nitrogen atoms, thus labeling the nitrogen would include all DNA and proteins. This being the main reason why Hershey and Chase decided to label the DNA instead.
