Which of the following statements is true? a. the main cause for speciation is an increase in gene flow. b. organisms that reproduce asexually are not considered part of a species. c. on a tree of life diagram, speciation is shown by the merging of two different lineages. d. the size of the geographic area inhabited by a population can cause speciation.
the right answer is D because i put C and i got it wrong please trust me on this one
B. Population of a species become isolated from one another
Explanation: Speciation can be simply refered to as the development of new species over the span of Evolution.
Speciation includes the parting of a solitary developmental heredity into at least two hereditarily autonomous ancestries. This can be possible if this species are seperated from one another by a barrier such as River, Mountains etc, to the extent that each species evolve separately and distinctly and it becomes impossible for them to breed even though they were initially from the same specie lineage.
C, If a population is spread out over too large area, they may become extinct.
A main cause of speciation is when species become geographically isolated.
Speciation refers to a process in which a population turns into a different species. One of the main causes of this is geographic isolation because when a population is separated because of a barrier like a river, this population adjusts to the specific environment and it becomes different from another population that can't breed with the members of this population.
hope this helps!
Hybrid organisms always produce sterile offspring.
If a population is spread out over too large area, they may become extinct.
