What would you expect to happen if a transfusion recipient had blood type o and a donor had blood type ab?
NNADVOKAT [17]

If a person with blood group type O received blood transfusion from type Ab it will lead to major hemolytic transfusion reaction.  

<h3>What is Blood Transfusion?</h3>

Intravenously putting blood components into a person's circulation is known as a blood transfusion. For a number of medical disorders, transfusions are performed to replenish lost blood components. The blood's components, such as red blood cells, white blood cells, plasma, clotting factors, and platelets, are now frequently used in transfusions instead of the whole blood that was used in earlier times.

Hemoglobin is a component of red blood cells (RBC), which carry oxygen to the body's cells. Although they are not frequently utilized in transfusions, white blood cells are an essential component of the immune system and help the body fight illnesses. The "yellowish" liquid component of blood called plasma serves as a lubricant and is made up of essential nutrients and proteins for the body's overall health.

Suppose 64 percent of people living in a remote, isolated mountain village can taste phenylthiocarbamide (PTC) and must, therefo
worty [1.4K]

Answer:

The percentage of the population that is heterozygous for this trait is 48%

Explanation:

They are two alleles, the phenylthiocarbamide tasters (PTC) and the non phenylthiocarbamide tasters (non PTC). PTC testers are dominant and non PTC tasters are recessive.

let the frequency of the dominant allele(A) be p

and the frequency of the recessive allele(a) be q

We are told that 64 percent of people living in a remote, isolated mountain village can taste phenylthiocarbamide (PTC) and must, therefore, have at least one copy of the dominant PTC taster allele (that is AA and Aa)

Frequency of AA = p², Frequency of Aa = 2pq and Frequency of aa = q²

Therefore p² + 2pq = 64% = 0.64

According to Hardy–Weinberg:

p² + 2pq + q² = 1 and

p + q = 1

Since p² + 2pq = 0.64

∴ 0.64 + q² = 1

q² = 1 - 0.64 = 0.36

q = √0.36 = 0.6

Since p + q = 1

p = 1 - q = 1 - 0.6 = 0.4

The frequency of heterozygous = 2pq = 2 × 0.4 × 0.6 = 0.48

Therefore the percentage of the population that is heterozygous for this trait is 48%
