Answer:

Option D, A subject is observed both before and after two exposures to the treatment.

Explanation:

In A-B-A-B design the alphabets have following meaning

a) First A – It is the baseline value or the value measured before treatment

b) First B – It is the treatment measurement

c) Second A  - It is the withdrawal of treatment  

d) Second B – It is the reintroduction of treatment  

The second A is known as the reversal phase in which the intervention is withdrawn to see if the target behavior returns to the baseline behaviour

Thus , there are two measurements involved one before the intervention and second after the intervention

Option D is correct

Why are there no carriers with dominant pedigrees?
elena-14-01-66 [18.8K]
You can't have a carrier with a dominant pedigree because other wise than individual or organism would be afflicted by the gene and render them incapable of being a carrier. A carrier is an individual/organism that has a normal phenotype (meaning it is not afflicted by said gene) but is carrying the gene that could cause disease or whatever the affect may be. In this case the gene would have to be homozygous recessive to be expressed. Hopefully this helps!
