Speller et al.(2010)analyzed turkey mitochondrial DNA haplotypes and reported that turkeys were domesticated by precontact native North American cultures in several independent events.Which of the following would be evidence of domestication of turkeys?

Question

Quizplus · Accepted Answer

Low genetic variation in turkey tissues found at settlement sites compared to wild turkey tissues would indicate a bottleneck effect, which is typical during the domestication process. This is because only a small number of individuals are typically used in the initial stages of domestication, leading to a decrease in genetic diversity. Option A is incorrect because high genetic variation in turkey tissues would suggest that domestication did not occur. Option B is incorrect because low genetic variation in wild turkeys does not necessarily provide evidence of domestication. Option D is incorrect because similar amounts of genetic variation in wild turkeys and domesticated turkeys would not support the hypothesis of domestication by precontact native North American cultures.
