Question

For human blood-allel of a gene is found so type of blood group is found. In these AB blood group is an example of, Blood group A & blood group B is an example of blood group O is a example of- & all blood group is a example of ------ Correct order of words for filling the blanks O 3, 4, codominance] dominance, homozygous ressiveness, multiple allel. O 3, 4, dominance, codominance, homozygous ressiveness, multiple allel. 4, 4, codominance] dominance, homozygous ressiveness, multiple allel. 3, 3, dominance, codominance] homozygous ressiveness, multiple allel.​

Answer 1

Explanation:

ABO blood group is best example to Codominance, Incomplete dominance and Dominance.

Codominance – expression of phenotypes of both parents is called codominance.

Multiple allelism – Presence of more than two alleles for a gene is called Multiple allelism.

Dominance – expression of one allele in pair of contrasting characters, in heterozygous organisms is called Dominance.

So, the correct option is ‘Both B and C’
