To answer these questions, you must know some of the basic terms first.

Terms you need to know:

  • Allele - a letter that represents a genetic trait.
  • Dominant - traits that shows and dominate the recessive allele.
  • Recessive - traits that are masked off or not expressed.
  • Phenotype - The physical trait. In this case, the blood type of an individual (Type AB, A, B, and O)
  • Genotype - The gene type of a person, which is represented by the alleles. ( AA, AO, BB, BO, AB, and OO)
  • Homozygous  - Trait that has two identical alleles. (Ex. AA, BB, OO)
  • Heterozygous - Hybrid which has two different alleles. (Ex. AB, BO, and AO)

So to answer your question:

1. What is the dominant allele for Blood type? How about recessive?

  • The dominant allele in the ABO blood system is alleles A and B, while O is the recessive allele.

2. What are the possible genotypes of blood type A?

  • From the table given, the possible genotypes of blood type A are AA and AO.

3. Which of the blood type/s has two possible alleles?

  • Blood type AB has two possible alleles -- alleles A and B.

4. What will be the possible blood type of the offspring if the parents have blood type A and Type B?

  • If both parents have dominant alleles for blood types A and B (meaning, the parents are homozygous AA and BB), then their child has blood type AB.

But certain cases where codominance will exist. For example, 'yung isang parents ay AO then yung isa ay homozygous BB, then possible 'yung child nila will have blood type AB and B.

This question seems incomplete. Please clarify if the parents are both homozygous for blood types A and B. If yes, then the final answer will be the first bullet.

5. What are the possible blood types of offspring if the parents have both Type AB blood types?

  • If both parents possess blood type AB, then the possible blood type of their offspring would be blood types A and B.

I hope this helps!

Answer:

Answers for guide questions:

1. Alleles A and B are dominant.

O is the recessive allele

2. Possible genotypes for blood type A are AA and AO genotypes.

3. Blood types with two possible alleles are type A and type B.

4. If the parents have a blood type A and Type B,

the possible blood type of the offspring will depend wether the parents are homogenous A and B or heterogenous. if both are homogenous for their blood types the offspring will have blood type AB, if both are heterogenous, the possible blood types of offspring will be AB, B and O, and if one is homogenous A and the other is heterogenous B the possible blood type of offspring will be AB and O,and if one is heterogenous A and the other is homogenous B the possible blood types of offspring will be AB and B.

5. The possible blood types of offspring if the parents have both Type AB blood will be Type A, type B and type AB.
