Vocabulary for Chapter 24 and 25 of Campbell Reece Biology 8th Edition for AP Biology.
129136679 | Reproductive Isolation | Existence of Biological Factors that impede members of two species from interbreeding | 0 | |
129136680 | Prezygotic Barriers | Before the Zygote Prevents Fertilization | 1 | |
129136681 | Habitat Isolation | When species do not encounter one another | 2 | |
129136682 | Temporal Isolation | When species mate or flower during different seasons or at different times of the day | 3 | |
129136683 | Behavioral Isolation | When a species does not recognize another species as a mating partner due to differences in courtship rituals, mating songs, pheromones, etc. | 4 | |
129136684 | Mechanical Isolation | When male and female genitalia are structurally incompatible | 5 | |
129136685 | Gametic Isolation | When male gametes do not survive in the environment of the female gametes, or when female gametes do not recognize male gametes | 6 | |
129136686 | Post-zygotic Barriers | After the Zygote Prevents a hybrid zygote from developing into a viable, fertile adult | 7 | |
129136687 | Hybrid In-viability | When a zygote fails to develop properly and dies before reaching reproductive maturity | 8 | |
129136688 | Hybrid Sterility | When hybrids become functional adults, but are reproductively sterile | 9 | |
129136689 | Hybrid Breakdown | When hybrids produce offspring that have reduced viability or fertility | 10 | |
129136690 | Allopatric Speciation | When a population is divided by geographic barriers so that interbreeding between the two populations is prevented. If the two gene pools diverge sufficiently, a new species can form | 11 | |
129136691 | Adaptive Radiation | Emergence of numerous species from a common ancestor | 12 | |
129136692 | Sympatric Isolation | Subdividing a gene pool when members of the daughter species are not geographically separated | 13 | |
129136693 | Earth Formed | 4.5 billion years | 14 | |
129136694 | Miller-Urey Experiment | Simulated early Earth atmosphere, produced organic compounds | 15 | |
129136695 | Protobionts | The precursors of cells; organic molecules enclosed in a membrane | 16 | |
129136696 | Endosymbiotic Theory | Mitochondria and Chloroplasts contain their own DNA, ribosomes, reproduce independently of their host cell in a manner similar to binary fission, have two phospholipid bilayers, and Chloroplast thylakoid membranes resemble photosynthetic membranes of cyanobacteria | 17 |
