Mr. and Mrs. Green have a daughter, Georgia, who was born at Riverside Community Hospital. Mr. and Mrs. Blue have a daughter, Be
Pani-rosa [81]

Answer:

Yes, Mrs Green is correct that Belle is her biological daughter

Explanation:

According to this question, Mr. and Mrs. Green is said to have a daughter, Georgia while Mr. and Mrs. Blue is said to have a daughter, Belle. Both daughters were born the same day. Hence, a controversy occured as Mrs. Green thinks that Belle is her biological daughter.

Based on the blood analysis, the following were obtained:

Mr. Green: Type A

Mrs. Green: Type A

Georgia: Type A

Mr. Blue: Type AB

Mrs. Blue: Type A

Belle: Type O

The genotype of the following blood types is as follows:

Type A - iAiA or iAi

Type B - iBiB or iBi

Type O - ii

Type AB - iAiB

From the analysis of blood types of Mr and Mrs Green, which are both type A, they can possibly produce a child with type A.

However, from the analysis of Mr. and Mrs. Blue, it is impossible to have a child with blood type O. However it is possible for Mr and Mrs. Green if they are both heterozygous (iAi × iAi). The punnet square is attached. Hence, Mrs Green is correct about her claim since Mr. and Mrs. Blue cannot have a child with blood type A.

Katyanochek1 [597]

Dr. Brantz wants to test the part of the brain which is active while lying. For this purpose, he will need to make use of the fMRI (functional magnetic resonance imaging) technique. This technique is used for measuring the brain activity by the means of the detecting changes in the blood flow. The neural activation affects the cerebral blood flow, and this change can be noticed using fMRI.

Hence, the answer is 'fMRI'.
