Homework Answers
Question 1. Answer B. Gene flow.
When a certain population of organisms get isolated and there is no gene flow between the population. These population then go under speciation and over time forms a different species having a common ancestor.
Question 2. Answer C. Allopatry
Allopatric speciation is the most common way of speciation. This means when the population of two similar species get isolated by some geographical or extrinsic barrier and that will lead to speciation and cause the formation of new speciation due to lack of gene flow.

During the evolutionary synthesis, biologists conclusively identified natural selection, gene flow, genetic drift, and mutation as the major causes of evolution within species. Using the scientific definition of evolution, explain how these forces cause populations, species, and higher taxa to evolve.

Which of the following is a correct comparison between the speciation of the trumpeters of the Amazon and the ongoing divergence of the maggot flies of North America? See Section 24.3 Both events resulted from barriers to gene flow that arose between populations as well as mutations, natural selection, and genetic drift that occurred in those populations. Both events involved a large geographic barrier between populations. Both events involved polyploidization. Both events involved populations that were overlapping in their ranges.

Select all that apply Founder Effect Gene Flow Natural Selection Mutation Genetic Drift6. There are two isolated populations - Population 1 and Population 2. These populations have been separated for a long period of time. Now, imagine that you bring individuals from these populations together to see if they will interbreed. You find that there is only limited interbreeding between Population 1 and Population 2 and...

this is an evolution question
Allopatric speciation is probably the most common way that new species form. Please describe a hypothetical scenario in which an initial ancestral population (pick whatever species you want) could split to form a new species through allopatric speciation. A fully. correct answer will at least incorporate ALL of the following terms: gene flow.divergence, natural selection (including sexual selection), genetic drift, and reproductive isolation

Which of the following statements about genetic drift as an evolutionary factor is true? a. It is more potent in a population with small numbers than in a population with large numbers. b. It is responsible for the selection of mutations. c. It is connected to the movements of alleles between populations of a single species. d. Its strength is proportional to the size of a population: the larger the population, the greater the force. e. Both a and b
