Question

ABO blood group in man is controlled by
A. Multiple alleles
B. Multiple cells
C. Sex-linked genes
D. V-linked genes.

Answer 1

The better featured instance of more than one allele in humans is the ABO blood types, mentioned in the Non-Mendelian Inheritance concept. Other human features decided via multiple alleles might be eye color, built, hair color, hair texture, bodily structures, etc.

Complete answer:
To answer this question, first, we need to know about the ABO blood group in man. The ABO blood grouping system is used to indicate the presence of one, each, or neither of the A and B antigens on erythrocytes. In human blood transfusions it is the maximum vital of the 38 other blood type (or group) categorization structures presently recognized. A mismatch (very uncommon in current medicine) in this, or any other serotype, can cause a probable unfavorable after a transfusion, or an undesirable immune response to an organ transplant.
Now, let us find the solution from the option.
A quantity of human characteristics is the cause of greater than two kinds of alleles. Such features are stated to have more than one allele for that trait.
Blood kind is a multiple allele characteristic. There are three other alleles for the blood type (A, B and O). A is dominant to O. B is dominant to O. A and B each are co-dominant.
It is not multicellular or includes more than one cell.
Sex linked is a trait wherein a gene is found on a sex chromosome. It is not always maintained by sex linked gene neither v-linked gene.

Hence, the correct answer is option(A).

Note: ABO blood grouping system, the class of human blood primarily based totally at the inherited characteristics of red blood cells (erythrocytes) as decided via the presence or absence of the antigens A and B that are carried at the base or surface of the red cells. Persons can also additionally therefore have type A, type B, type O, AB blood. The A, B, and O blood groupings had been first recognized via Austrian immunologist Karl Landsteiner in 1901.
