Match up Vocabulary

Match up a vocabulary term with a definition and then with an example. Be aware that some examples and even definitions may apply to several vocabulary words but there is a "more correct" answer for each term.

Vocabulary Term:
  • Directional Selection
  • Stabilizing Selection
  • Disruptive Selection
  • Artificial Selection
  • Phenotypic Plasticity
  • Intrasexual Selection
  • Intersexual Selection
  • Industrial Melanism
  • Spontaneous Generation
  • Transmutation
  • Variational Evolution
Definition:
  • Simple animals arise from raw meat, piles of rags, or fruit
  • One extreme phenotype is more successful in the environment
  • Selection that occurs between two males within a population
  • Natural Selection: Individuals don't change but instead there's a change in population allele frequency due to variation of individuals
  • Inheritance of Acquired Characteristics: Individuals pass on the phenotypic changes acquired during their life
  • Model for natural selection in which humans choose what variations are "fit"
  • Both extreme phenotypes have higher fitness than the average phenotype
  • Selection that occurs between males and females in a population
  • Increased rates of darker phenotype in a population of moths
  • Two different environments will lead to two different phenotypes in the same genotype
  • The average phenotype is more successful in the environment
Example:
  • Larger female frogs reproduce more often and produce more offspring causing a shift average female body size in the population
  • Disproved by Louis Pasteur in 1862
  • Humans create different levels of hemoglobin at different elevations
  • Poodles have been bred to be hypoallergenic for humans with allergies
  • Intermediate sized male fish are unable to defend space for breeding like the large males and unable to "sneak fertilize" like the smaller male fish
  • Male birds of paradise have bright colors that help to attract a female within the population
  • Rabbits that turn white more quickly than other rabbits in the population will be more likely to survive and reproduce, thus passing on this "quick changing" variation to their offspring
  • Mountain goats compete with head butting for breeding rights with the females in the population
  • Both low and high birth weights in human babies have increased death rates
  • During the industrial revolution darker moths became more frequent in the population due to increased predation of lighter colored moths on dirty trees
  • Parent giraffes that were able to stretch their necks the longest will be more likely to reproduce and will pass this longer stretched neck onto their offspring
