In a small island population of birds, a rare genetic mutation causes some individuals to have unusually long tail feathers. Over several generations, this trait becomes much more common in the island population than in the mainland population. Which of the following best explains this change in allele frequency

This question asks us to explain why a rare genetic mutation for long tail feathers becomes more common on the island over generations. Since the options provided are unavailable, I will first discuss the core idea and then outline why genetic drift fits best conceptually.
In small populations, allele frequencies can change from one generation to the next simply due to random sampling of alleles when......Login to view full explanation登录即可查看完整答案

Question at position 12 Based on the reading from class on Australia's endangered quolls, these small mammals have suffered declines from various threats, including cane toads, habitat loss, and predation that dramatically reduced local populations. Which of the following is a key genetic risk for these small, endangered quoll populations?Smaller populations are more likely to acquire harmful mutations.Small populations are at risk of suffering from "over selection," where natural selection starts to remove adaptive traits.Small populations are more at risk of genetic drift, which can erode genetic diversity.Increased gene flow from other regions can dilute adaptive traits.Clear my selection
The table provides information on two populations, Population 1 on the left and Population 2 on the right, in 2 years, 1980 and 2010. The first row has column headers from left to right: Year, Allele uppercase R and Allele lowercase r for Population 1, and Allele uppercase R and Allele lowercase r for Population 2. The data in the next two rows are as follows, from left to right: Row 2: 1980, Population 1: Allele uppercase R, 0.3; Allele lowercase r, 0.7. Population 2: Allele uppercase R, 0.37; Allele lowercase r, 0.63. Row 3: 2010, Population 1: Allele uppercase R, 0.0; Allele lowercase r, 1.0. Population 2: Allele uppercase R, 0.75; Allele lowercase r, 0.25. The table shows the changes in allele frequencies of a specific gene in two populations of randomly mating small mammals after 30 years. The populations inhabit adjacent equatorial islands that have similar topography and climate. Which of the following is the most reliable conclusion that can be drawn from analysis of the data above?
