Genetic drift refers to ________.Question 10Select one:A.a change in the relative abundance of a species' occurrenceB.a change in the relative abundance of genes in a population because of tectonic plate movementC.a change in the relative abundance of a population's genes because of mutationD.a change in the overall distribution of a populationE.a change in the relative abundance of a certain inherited trait within a population brought about by a chance event

In which populations does genetic drift most often occur

Genetic drift is a change in allele frequencies that occurs by ______ and, unlike mutations, it tends to eliminate alleles from the population.Multiple choice question.chancedirectional selectionnatural selectionrandom mating

Why is genetic drift more likely to occur in smaller populations?

Genetic drift is Blank______.Multiple choice question.gradual changes in gene frequency due to random eventsa loss of genetic diversity due to a catastrophic event where few members of a species survivethe maintenance of gene frequencies between generationsthe theory that smaller islands tend to have fewer species

In a hypothetical population of endangered turtles, a few individuals find themselves abandoned on an island. Due to the scarce resources and little genetic contact with populations of mainland turtles, their population size has remained modest over numerous generations. As a result, the island population develops distinct genetic traits. Which of the following sums up the idea of genetic drift in this population of isolated turtles the best? Genetic drift is responsible for the island population's increased genetic diversity, promoting adaptation to the unique island environment Genetic drift is the mechanism behind the emergence of unique genetic characteristics in the island population, due to random fluctuations in allele frequencies Genetic drift occurs when the island population actively selects traits that enhance their survival, leading to genetic divergence Genetic drift and natural selection are synonymous in this scenario, as they both contribute to the island population's unique genetic features
