Bio 100 Exam 3 (Jaeger UNLV); Questions &
Answers 100% Verified
Evolution Correct answer-Any genetically based change of phenotype in a population
over successive generations
Common Decent with Modification Correct answer-species undergo modification
through successive generations
changes in species can lead to formation of new, separate species
Species Correct answer-different kinds of organisms
individuals of the same species share genetic similarity and can potentially interbreed
population Correct answer-all the individuals of the same species occupying a specific
area over a particular time
Fitness Correct answer-successful reproduction - leaving behind copies of yourself
natural selection Correct answer-agent of evolution
the process through which a trait or character that confers reproductive advantage to an
individual spreads in a population over successive generations
biotic potential Correct answer-most populations are capable of producing more
offspring then can be supported by the environment
, Bio 100 Exam 3 (Jaeger UNLV); Questions &
Answers 100% Verified
heritable Correct answer-pass it onto the next generation
overtime... Correct answer-the beneficial traits spread through the population
Competition for natural selection Correct answer-genetic traits that provided an
advantage will be spread within a population, but those tat do not will be lost from the
population
What evolves? Correct answer-populations
Evolution of acquired characters Correct answer-overtime, an organism could acquire
enough changes that one species could diverge into two
this branching extended back in time, ancestral species to ancestral species and so on
Five agents of evolution: Correct answer-natural selection
sexual selection
gene flow
genetic drift
mutation
, Bio 100 Exam 3 (Jaeger UNLV); Questions &
Answers 100% Verified
mutation Correct answer-a change in DNA sequence
mutation is Correct answer-the means by which new genetic information is
generated...most are detrimental or harmless, but a rare few are beneficial to an organisms
fitness
beneficial mutation Correct answer-building blocks of evolutionary change
whose theory was "Shorter Neck Giraffes Dieing" Correct answer-Darwin's Theory
gene flow Correct answer-the movement of alleles from one population to another by
migration
gene flow introduces Correct answer-'novel' alleles to a population from some other
population
genetic drift Correct answer-chance alteration of allele frequencies in a population
founder effect Correct answer-colonization of new habitat y a few individuals that give
rise to a new population. note: founding individuals do not represent the total genetic variation
in original population
