Answer:

The reason why an AB parent usually does not have an O child has to do with how blood type normally works genetically. Remember, we have two copies of each of our genes – one from mom and one from dad. This is true of the blood type (or ABO) gene as well. The ABO gene comes in three varieties: A, B, and O.

Answer: This is because a parent with type AB blood has both A and B antigens therefore, the child must inherit either A or B antigen from the parent.

Explanation: In ABO blood type, blood types are classified on the basis of the antigens present in the red blood cells. There are two types of antigens: A and B antigens.

A blood type is so named because it has A antigens, B blood type has B antigens, AB blood type has both A and B antigens while O blood type has no antigens.

Each of these blood types is controlled by two alleles, and children inherit one allele from each parent. If a parent has AB blood type, none of his offsprings will have O blood type because each offspring must inherit either antigen A or B from this parent.

Vitek1552 [10]

In this case, it is given that <em>Mycoplasma pneumoniae </em>lacks cell wall. some antibiotics such as penicillin works by interfering the synthesis of the cell walls. As these microbes do not have cell wall, the penicillin like antibiotics would not work.

In this case, the antibiotics, which interferes with the DNA (deoxyribonucleic acid) formation and replication can work. The ciproflaxin is an antibiotic, which work by inactivating the enzyme required for DNA replication in bacteria. Hence, the antibiotic ciproflaxin would be effective for treating the given condition.
