In case of ABO blood grop allele I^(A)and I^(B) if present together then-

Which one of them is the correct statement w.r.t a gene and an allele? a) There is one allele for a given gene which is located at a single loci in the homologous chromosome. b) An allele is the unit of DNA responsible for the appearance and inheritance of a character. c) An allele refers to section of DNA that controls certain traits, e.g., blood group type. d) None of these.

Inheritance of blood group is a condition of (a) Codominance (b) Incomplete dominance ( c) Multiple allelism (d) Dominance

Assertion :-The unmodified allele, which represents the orginal phenotype is the dominant allele and the modified allele is generally the recessive allele. Reason :- The modified allele could be responsible for production of a non functional enzyme or no enzyme at al.

On which chromosome set of 3 multiple alleles for four blood types are present?

Assertion : ABO blood group system provides a good example of multiple alleles Reason : In ABO blood group system, when I^(A) and I^(B) alleles are present together, they both express their own types

Theoretically, the modified allele could be responsible for the production of A. a non functional enzyme B. normal or less effecient enzyme C. No enzyme at all
