Amother has blood type a and her son has blood type o. which blood types are possible for the father?

Question asked:A mother has blood type A and her son has blood type O. Which blood types are possible for the father?

usually if one parent has one blood type that is different then their child like the mother having type A and then the child having type O. One parent probably passes a type O allele.

So the father more than likely has type O like the child

A, B or O

Explanation:

The ABO blood type is regulated by three alleles of gene "I". The genotype "ii" gives blood type "O". Since the son of the given parents have blood type "O" (genotype: ii), both parents should have one copy of "i" allele.

Hence, the possible genotype and respective phenotypes for the father are:

1. IAi (A blood type)

2. IBi (B blood type)

3. ii (O blood type)  

interphase   is the cell cycle stage in which the cell acquires nutrients, creates and uses proteins and other molecules and starts the process of cell division by replicating the dna. it is the longest stage in the eukaryote cell cycle.

the following   can go wrong during interphase:   a base pair could be mismatched during the duplication process causing a mutation.   correct answer: c
