Susan, a mother with Type B blood, has a child with Type B blood. She claims that Craig, who has
laiz [17]

Answer:

A child with type B blood can have a mother with type B blood and a father with type O blood so the judge grants her request and decides due to Susan is right and Craig must pay child support (option b).

Explanation:

Susan is right in this case because her <u>son with type B blood may have a mother with type B blood and a father with type O blood</u>.

Blood types, according to the ABO system, depend on the existence of surface antigens A or B —Types A, B and AB— or their absence in the erythrocyte membrane.

In the inheritance of blood groups A and B are co-dominant, while the absence of antigens —type O— is a recessive trait.

Assuming that Susan has a genotype B/B and that Craig has a genotype O/O:

<em>Alleles      O     O </em>

<em>B            B/O  B/O </em>

<em>B            B/O  B/O</em>

So it is very likely that the child is Craig's son and Susan is right.

Think about the dna coding sequence of a gene. if an a were swapped for a t, what kind of mutation could it cause and why? think
vekshin1
Hi, 

I think the answer you're looking for is already in the question you submitted. However, I disagree that a frameshift could result from the mutation because frameshifts would only happen if there were insertions or deletions in the sequence. For your question, this is an example of a simple point mutation/nucleotide base substitution, and would only result to either a missense or a nonsense mutation. Depending on the bases flanking your mutation, this results to transcribing a different sequence of RNA leading to translating either a different amino acid or a stop codon.
