Prior to European colonization, over 50 million bison lived across North America. By 1882, due to overexploitation by European colonists, the bison was virtually extinct, with the total population in North America numbering around ~500 individuals. Since then, careful conservation efforts have increased the North American bison population to over 300,000 today. As a result of this catastrophe, bison experienced a “population bottleneck”, which is a severe form of . As a result, the current population should be expected to have , relative to the pre-colonial population.

CHOOSE THE BEST ANSWER A mother and her two daughters each develop breast cancer at approximately the same age in their lives. Based on genetic analysis, it is determined that mutations in the BRCA1,  tumor suppressor gene, is responsible for all three instances of cancer. Their specific mutations are presented below (bold base pair). Mother: ATCGGTCCADaughter A: ATCGGTCCADaughter B: ATCGCACCA Given these data, what is the most likely origin of each daughters’ cancer? Daughter A’s cancer is Daughter B’s cancer is
