Upоn genetic аnаlysis оf the cаncerоus tissue, a single mutant copy of a gene, named the Peach gene, was discovered in all affected individuals but not in the unaffected individuals. Because so many members of the family are affected, the female (age 70), indicated with a “*”, is concerned that although she has not developed the disease yet, she still may develop the cancer later in life. What would a genetic counselor tell her? A new form of blood cancer was identified in a family in which many of the family members were affected. This family's pedigree is shown below. *
A trаnsfоrmаtiоn experiment is perfоrmed with а donor strain that is resistant to four drugs, A, B, C, and D, determined by genes A, B, C, and D. The recipient strain is sensitive to all four drugs. The treated recipient-cell population is divided up and plated on media containing various combinations of the drugs. A cell that is resistant to the added drug(s) will form a colony. The table below shows the results. Drug(s) Added Number of Colonies Drug(s) Added Number of Colonies None 10,000 BC 51 A 1,156 BD 49 B 1,148 CD 786 C 1,161 ABC 30 D 1,139 ABD 42 AB 46 ACD 630 AC 640 BCD 36 AD 942 ABCD 30 One of the genes is quite distant from the other three that are tightly linked. What is the probable order of the three tightly linked genes? Explain your answer
