Question | Answer |
Evolution | the process in which population changes over time |
What are the types of evolution? | microevolution and macroevolution |
Microevolution | evolution or change on a small scale |
Macroevolution | evolution or change on a large scale |
Population Genetics | the science that studies the change in distribution of traits within a species population (A.K.A gene pool) |
Species | Organisms that are so genetically similar that they have the potential to breed and produce that are viable and fertile |
Viable | living |
Fertile | able to reproduce eventually themselves |
What four criteria is population defined by? | Same species of organism Located in the same location At the same time And showing signs of reproduction (offspring is present within the group) |
Geographic Range | the geographical area within which a species can be found |
Organisms that are common may have... | several populations that cover a wide range |
What is one example of a range that is global? | humans |
Geographic Barriers | large mountains or bodies of water |
Do individuals evolve? | no; but populations do |
Can you change DNA? | no |
Mutations | random changes that occur in an organism’s DNA. Some help individuals survive in their environment and reproduce and some do not. Other mutations have no effect |
If a mutation (change) occurs in the DNA of sex cells (gametes) of the parent(s) then what happens? | changes can be inherited by the offspring |
Allele Frequency | how many alleles are present at that time within the population |
Fixed | there is no change in frequency; no evolution is present (a state of equilibrium) |
Evolving | frequency is changing; evolution is occurring (a state of change over time) |
There are always how many traits for an allele? | 2 |
