In a maternity ward, four babies become accidentally mixed up. The ABO types of the three babies are known to be A, B, and AB. The ABO types of the four sets of parents that are clamed are determined.
(A) AB X O (B) A X O, (C) A X AB, (D) B X O.
Following some statement is given
A. A blood group baby must be child of Parent B
B. B blood group baby must be child of Parent A
C. AB blood group baby must be child of Parent A

geneticist is working with a new bacteriophage called phage Y3 that infects E. coli. He has isolated eight mutant phages that fail to produce plaques when grown on E. coli strain K. To determine whether these mutations occur at the same functional gene, he simultaneously infects E. coli K cells with paired combinations of the mutants and looks to see whether plaques are formed. He obtains the following results. (A plussign means that plaques were formed on E. coli K; a minussign means that no plaques were formed on E. coli K.)
How many cistron belong to these mutation?
