A transformation experiment is performed with a donor strain that is resistant to four drugs: W, X, Y, and Z. The recipient is sensitive to all four drugs. The treated recipient population is divided up and plated on media containing various combinations of the drugs. The table below shows the results: Drug(s) added Number of Colonies None 20,000 WX 76 WY 1324 WZ 1976 XY 85 XZ 69 YZ 1564 WXY 50 WXZ 62 WYZ 1354 XYZ 48 WXYZ 53 Following observation are given A) X gene is obviously quite distant from the other three genes B) Y gene is obviously quite distant from the other three genes C) The Order is three closely link gene W Z Y D) The Order is three closely link gene W X Z Which of the following combination is correct? -triyambak.org
