Evolution: 22,23,24
| Question | Answer |
|---|---|
| Aristotle is to Scala nature as...Carolus Linnaeus is to.... | Carolus Linnaeus is to binomial nomenclature. |
| Lamarck summarized his work into 2 principles:Principle of use and disuse and inheritance of acquired characteristics. which prinicple is false and why? | |
| Out of 4 obervations made by Charles Darwin made what two inferences was made from those observations? | That some individulas tratis give them a higher chance of suriving and reproducing in a given enviorment. unequal reproduction will lead to accumlation of enviromently favorable traits in a population over generations. |
| Evidence to show us how species of different organisms have evolved is? | fossils. |
| True or False: Populations do no evolve. individuals evolve. | false; populations evolve and individuals do not. |
| What are three ways that allele frequency can be altered in a population? | 1. natuarl selection 2.gentic drift 3.gene flow |
| True of False: natural selction only acts on a n organism's phenotype. however, will affect the genotype of future generations. | True. |
| What does the biological species concept say about species? | that a group of populations that can interbreed in nature and produce viable, fertile offspring. |
| There are 8 major wasy that reproductively isolationcan occur. which are prezygotic and which are postzygotic? | prezygotic: habitat isolation, temporal isolation, mechanical isolation, gametic isoloation, and behaviral isolation Postzygotic: reduced hybrid viability, redyced hybrid fertility, hybrid breakdown |
| what are the two ways of measuring genetic variation in a population? | by the whole-gene level(gene variability) and hte molecular level of DNA (nucleotide variability) |
| What are the 8 major ways that reproductively isolation can occur? | habitat isolation, temporal isolation, mechanical isolation, gametic isolation, behavorial isolation, reduced hybrid viability, reduced hybrid fertility, and hybrid breakdown |
| What are the conditions for Hardy-Weinberg equilibrium? | 1. no mutations 2.no natural selection 3.mating is random 4.no gentic drift 5. no gene flow |
| Analogous structure are similar problems but do not indicate that they are related. What is and example of a analogous structure? | bird wing, butterfly wing |
| What is required for the formation of new species? | mutations |
| if a species is a group of populations whose members have potential to breed in nature to produce fertile offspring. What is a hybrid? | a hybrid is an offspring that will result from an interspecific mating. |
| Hybrids are offspring that result from an interspecific mating. So a hybrid mating zone is what? | it is a region in which members of different species meet and mate, producing at least some offspring of mixed ancestry. |
