The frequency of sickle-cell anemia, an autosomal recessive condition, is 0.007. Assuming that the population is in H-W equilibr
damaskus [11]

Answer:

The correct answer is - 0.084

Explanation:

Sickle cell anemia is a autsmal recessive blood disorder of RBCs where RBC shape altered to the sickle shape or cresecent moon that obstruct and damage the veins and artries.

Normal allele is represented by - HbA - p

sickel cell allele is represented by - HbS - q

genotype frequency of normal allele HbA in the population = p2

genptype frequency of HbAHbS in the population = 2pq

genotype frequency of autosomal recessive HbS = q2 = 0.007 (given)

So, the allelic frequency of the recessive allele =

q =  √ 0.007 = 0.08366 or 0.084

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.

NemiM [27]

Temporary storage sites in the cytosol for substances such as pigments or nutrients are called inclusions.

Pigments are the compounds that have a certain color and provide color to other structures indie the body. For example in plants chlorophyll is the pigment that provides green color to the leaves and stem. In humans and other animals, the blood consists f red colored pigment called hemoglobin.

Inclusions are the non-living objects inside the cell. They can be anything like pigments or any other molecules, that performs no function inside the cell. They are also called ergastic substances and do not even have any membrane.
