The prompt presents the question: '22. SARS-CoV-2 evolves through which of the following processes?' and indicates the selected answer is 'Drift', but the provided answer_options field is empty, so there are no alternative choices to evaluate here. First, consider what drives viral evolution in general. Viruses evolve through several interconnected mechanisms, including mutation (random changes in the viral genome), genetic drift (random fluctuations in allele frequencies due to sampling effects in small populations), natural selection (preferential replication of variants that confer a fitness advantage), recombination (exchange of genetic material when a co-infecting virus is present), and some......Login to view full explanation

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

The process of genetic drift describes

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?
