Concept Of Dominance|Incomplete Dominance|Codominance|Difference Between Codominance And Incomplete Dominance|Codominance - ABO Blood Group

Considering ABO blood grouping system in humans, during blood transfusion some combinations of blood groups are compatible (sqrt") whereas the others are incompatible (X). Which ONE of the following options is COR- RECT ?

(i) Human beings have three alleles for ABO blood grouping |A||B| and i . How many of these alleles can be present in one individual and a gamete ? (ii) A child has blood group B. If the mother has blood group AB and father blood group A workout the genetypes of the parents and the possible genotypes of the other offsprings.

In human beings, 'ABO' Blood group is controlled by which gene ?

Inheritance pattern of ABO blood group in human shows dominance, co-dominance and multiple allelism. Explain each concept with the help of blood group genotypes

Assertion (A) : ABO blood group in human being is an example of multiple allelism. Reason ( R): It has three alleles for the gene 1 i.e. I_(A),I_(B),i .

Match the items given in column I with appropriate items (one or more) of Column II: {:(,"Column I",,"Column II"),((1),"ABO Blood groups in man",(a),"Polygenic inheritance"),((ii),"Skin colour in man",(b),"Multiple phenotypic effects"),((iii),"Pleiotropy",(c),"Monohybrid cross"),((iv),"Law of segregation",(d),"Multiple allelism"),(,,(f),9:3:3:1),(,,(g),"Codominance"):}

Match column I with column II and select the correct option from the given codes {:(,"Column I",,"Column II"),("A.","Dihybrid test cross","(i)",9:3:3:1),("B.","Law of segregation","(ii)","Dihybrid cross"),("C.","Lawof independent assortment","(iii)",1:1:1:1),("D.","ABO blood group in man","(iv)","Purity of gametes"),(,,"(v)","Multiple allelism"):}
