Orgin Of Species Flashcards
This isolation is when the two species are separated by where they live. (Water/land)
Habitat isolation
The appearance of a new species is called?
Speciation
This isolation is when they breed at different times of the year?
Temporal isolation
This isolation is when there is a certain dance or something else that needs to be done in order to mate
Behavioral isolation
This isolation is when a species needs to have a certain look or a certain structure in order to mate?
Machanical isolation
This isolation is when the sperm doesn’t work with the egg. Or with the sea anemia it kills off other sperm with it’s own
Gametic isolation
This type of postzygotic barrier makes it so the hybrid is weak and is unlikely to reproduce
Reduced hybrid viability
This type of postzygotic barrier is when the hybrid is forbidden to reproduce
Reduced hybrid fertility
This type of postzygotic barrier is when the hybrids future offspring is weakend indefinitely.
Hybrid breakdown
Allopatric speciation is when?
A species gets separated by a geological barrier from it’s original population and evolves to be another species
Sympathetic speciation is?
When a species evolves from it’s original population without a geologicAl barrier
Is the evolutionary rate or timing of an organisms development
Heterochrony
This is the title for different rates of growth for different body parts
Allometric growth
Homeotic genes do what?
Determine where body parts are located!
Hoc genes are?
Class of homeotic genes that provide positional information. If it is expressed in the wrong location you could have hands coming out of your asshole!!
