How can reproductive barriers form sympatric populations while their members remain in the same geographic area?Question 10Select one:a.increased gene flowb.polyploidyc.decreased sexual selectiond.habitat sharing

Which of the following statement is NOT TRUE about sympatric speciation? *1 pointChanges in genome reproductively isolated the subpopulation from the parent populationGeographical barrier prevents gene flow between subpopulationOrganisms occupy geographically overlapping areasHybridisation causes formation of new species

What process may lead to speciation when a population adapts to its environment, and as an incidental consequence of that, becomes reproductively isolated from other populations?Multiple choice question.Natural selectionPolyploidyA population bottleneckGenetic driftThe founder effect

Which of the following scenarios would NOT result in genetic flow?Select one:a.A population of deer with thick coats lives in a colder northern climate. Due to high habitat loss, these deer migrate south and successfully mate with another population of deer with thinner fur coats.b.Pollen from a population of white poppies is spread to a population of orange poppies by hummingbirds that drink the nectar from both poppy populations.c.A species of green beetles is in an agricultural cargo shipment and is relocated to a new habitat to thrive.d.A population of finches on the mainland interbreeds with the population of finches on

Knowledge on populations requires understanding of the concept of the gene pool. The following are true regarding the relationship between populations and gene pools, EXCEPT:a.An individual can become part of the gene pool if that individual can share alleles with the other members of the population.b.The gene pool is simply the collective term referring to the entire genotypes entailed in a given population. c.Individuals who are not products or are not involved in the process of sexual reproduction are excluded from the gene pool. d.Small populations tend to interbreed and therefore decrease genetic variation, primarily because of the unshared gene pool.

Which of the following is an example of sympatric speciation?Group of answer choicesA population of butterflies prefers oranges. At some point, part of the population develops a preference for bananas. Eventually, the two groups no longer interact to the point that they no longer breed.A population of squirrels is split when a valley is formed, splitting their habitat into two. The valley prevents the squirrels on both sides from meeting and interbreeding.Two populations of fish compete for the same resources in a pond. After several years, the two populations of fish begin mating with one another and produce hybrids.None of these
