- Which statement about prezygotic barriers is false? A.They can arise from the evolution of the structure of sexual organs. B.They can arise from the specific interaction of plants with insect pollinators. C.They can arise from mate selection behaviors. D.They can arise from low fertility of hybrids.arrow_forwardWhich of the following are post-zygotic reproductive barriers?a. Different mating songs prevent mate recognitionb. Species A breeds in Spring, Species B breeds in summerc. Species A and B mate, but the embryos die before hatchingd. The gametes of species A aren’t compatible with the gametes of species Be.

- 1. Sea urchins are broadcast spawners that release clouds of sperm/eggs into the water column. However, the ability to successfully fertilize the egg by the sperm is restricted to very specific gametic proteins that inhibit cross species fertilization. This is an example of a a. Post zygotic barrier b.Habitat isolation c.Mechanical isolation d.Pre zygotic barrier e.Hybrid breakdownarrow_forwardWhich of the following traits does not describe a r-selected species? A. rapid development B. low parental investment C. high reproductive rates D. short life spans E. late maturationarrow_forwardWhich of the following terms best describes the biological scenario where species that look similar in allopatry look different in sympatry? a. Character displacement b. Tempo c. Fusion d. Post-zygotic barriersarrow_forward
- Which of the following situations has revealed that mutualistic interactions can evolve from prior parasitic relationships? A. Yucca plants are pollinated only by moths of the genus Tegeticula; however, some of the moth species 'cheat" by laying eggs on seeds without pollinating the plant. B. Large-sized lice of the genus Columbicola tended to live on larger species of pigeons. Body size matching had a significant effect on the ability of lice to escape defensive preening by the host bird. C. The nonvenomous yellow-eyed salamander has the same coloration as the toxic California newt. Related nontoxic salamanders which do not mimic the newts are prone to attacks by predators. D. Glochidion trees and Epicephala moths are in an obligate mutualism with each other. Significant cospeciation led to an increase in diversity of the two species.arrow_forwardWhich of the following statements does not support the conclusion that giraffes are k-selected species? a. Giraffes are approximately 6’ tall and weigh 150 lbs at birth. b. Wild giraffes begin mating at 6-7 years of age. c. Newborn giraffes are capable of coordinated walking within an hour of birth, and running within 24 hours of birth. d. Giraffes rarely give birth to twins.arrow_forwardOptions are a. Hybrid offspring. b. Speciation c. Adaptive radiation. d. Mechanical isolation.arrow_forward
