Bioscience II Exam 1

Questions: 37 | Attempts: 172 | Last updated: Feb 10, 2025

Sample Question
Among "Gypsies" (the Roma) there is a mutation (1267de1G) that is particulary common. Individuals identified as Roma live at varioous locations in the Old world. Statistical analysis dates the mutation's arrival in the population to ~1000 years ago. The mutation is otherwise found only in families of Indian or Pakistani origin, supporting the theology that the Roma originated there. One would predict that the reason for its much higher incidence among the Roma than among Indians or Pakistani is

Genetic drift is the small populations of the Roma

Gene flow from India and Pakistan to the various parts of the world where the Roma live

Higher levels of inbreeding in the small populations of the Roma than are found in the much larger breeding populations in India or Pakistan

Tow of the above are liely explantions

None ofthe above is correct

Sample Question
Some dogs have erect ears; others have drooping ears. Some dogs bark when following a scent; others are silent. Erect ears and barking are due to dominant alleles located on different chromosomes. A dog homozygous for both dominant traits is mated to a droopy-eared, silent follower. The expected phenotypic ration in the F1 generation is

9:3:3:1

100 percent of one phenotype

1:1

1:2:1

None of these
