Question 7 (1 point) 100 09 DRC 1999 Ravn, Kenya 1987 Marburg 94 Ozonlins, Zimbabwe 1975 07 DRC 1999 05 DRC 1999 1379c Angola 2005 Popp, UgandalGermany 1967 Musoke, Kenya 1980 90 100 Zaire, Yambuku 1976 Zaire, Kikwit 1995 96 Cote d'ivoire, 1994 Bundibugyo, Uganda 2007 Sudan, Gulu Uganda 2000 Reston, USA 1989 Ebola 100100 5 substsite 100 You can tell from the branching pattern that the Bundibugyo, Uganda 2007 strain of Ebola is more closely related to the Cote d'lvoire 1994 strain than to either of the Zaire strains. Knowing this, is the Bundibugyo, Uganda 2007 strain more closely related to the Zaire Yumbuku 1976 strain or the Sudan, Gulu Uganda 2000 strain? Zaire, Yumbuku 1976 strain Sudan, Gulu Uganda 2000 strain Equally closely related to both

Answer 1

Answer 7. Bundibugyo, Uganda strain 2007 more closely related to Zaire Yambuku 1976 as it shares most recent common ancestor with Bundibugyo.

Common ancestor for Bundibugyo, Uganda strain 2007 and Zaire Yambuku 1976 most recent than common ancestor of Bundibugyo, Uganda strain 2007 and Sundan, Golu Uganda 2000 strain.

2 species are more related if they have a more recent common ancestor (MRCA) and less related if they have a less recent common ancestor (LRCA).

Answer 8. Zaire, Kikwit 1995 experienced more evolutionary changes than Reston USA 1989. This is because there were more repeated branching events from common ancestor in the formation of Zaire, kitwit 1995 strain formation.
