- sexual selection
- mutation meltdown
- a Person who noticed similarity in shape and design among certain organisms, classifying organisms
- b change in in structure of a gene or chromosome, only way to create new alleles
- c on average the affects of mutations are deleterious, an accumulation of deleterious effects
- d observed new, diffferent species, visited many islands, observed gradual change, natural selection, adaptation,etc. Credited for idea of evolution.
- e natural selection that is related to mating success includes the ability to locate males, courtship behaviors, ornaments the mates find attrative, etc.
5 Multiple choice questions
- type of selection favors individuals at opposite ends of the phenotypic range
- Person who discovered that fossils change over time, noticed geological change, thought a series of catastrophies were responsible for the change in oraganisms
- The changes a parent accumulates during their lifetime can be passed to their offspring, mechanism of change (giraffe example)
- pre-zygotic factor that prevents mating because of different mating calls/rituals/dances/displays,etc.
- Idea of adaption and evolution, not made famous by discovery
5 True/False questions
founder effect → a few individuals are seperated from the source population. These individuals become founders of a new population. The allele frequencies are unlikely to match those of the source population, therefore, drift occurs. It unlikely that the small group contains all the alles of the large population. RANDOM
alleles → Idea of adaption and evolution, not made famous by discovery
temporal isolation → pre-zygotic factor that prevents breeding becuase of different mating times/seasons
trade off → a trait that operates in opposition to standard survival based selection. Ex. a loud call helps attract mates, but alerts predators to location
microevolution → variation in heritable traits within a population plus differential survival/reproduction = change in traits in a population over time
