1: What happened with Diane Dodd and the fruit flies? How did she create reproductive isolation?
She put two different types of flies and fed them different She created reproductive isolation by making two diffrent species
2: What is the definition a species?
Species is a type of animal that have different characteristics from other animals
3: What are the two main types of barriers in reproductive isolation?
Two main types are Physical (Geologic) and pre/post-zygotic
4: What is gene flow? What is reproductive isolation?
Gene flow is genes passing through generation and making it stronger
5: What is geographic isolation? (Give an example).
It is when a species is isolated because of were they live an example is Ulmis Pulima
6: What is allopatric speciation? (give an example)
It is when two species live in different places ans example is the meta lark
7: What is sympatric speciation? (give an example)
It is two species that live in the same land and example is chromosomes
8: What is peripatric/parapatric speciation? (give an example)
It is when the species have only part difference in DNA an example is the african elephant
9: What are pre-zygotic barriers? Name the types of pre-zygotic barriers (explain each). (Temporal, Mechanical, Behavioral)
Pre-zygotic barriers are things that grow first than zygote The types of pre-zygotic are temporal which is allowing them to breed, Behavior which is living in hybrid zones, and lastly Mechanical which is species that can't breed because their sexual organs can't get close to each other to breed.
10: What are post-zygotic barriers? Name the types of post-zygotic barriers- give examples. (Zygote Mortality, Hybrid Sterility)
Post-zygotic barriers occurs when zygotes are going to die the types of post-zygotic are Zygote mortality which is when sperm is transffered but the zygote will die instantly, the other one is Hybrid sterility which is when two different species breed to make a different species
11: What is polyploidy? What happens? Where is this common?
It is when an organism is unable to breed it mostly occurs in plants
12: What is the theory of Punctuated Equilibrium?
The theory is that speciation doesn't gradually happen over time, but rather very quickly.
