What is the main factor that leads to speciation between two populations?
Lack of exchange of genetic information.
What are the main steps of photosynthesis?
There are two main steps. They are dark reaction and light reaction.
What are the two main types of isolation?
That would be geographic isolation and reproductive isolation. Both could lead to speciation.
What are three events that can lead to speciation?
Species (phylogenetically and genetically distinct animals from a common ancestor) form when barriers exist to prevent outbreeding. These are usually environmental (e.g. mountain ranges, oceans, climatic barriers) or biological (e.g. interbreeding of two species results in an infertile offspring).
What is one of the main causes of speciation?
geographic isolation and the reduction of gene flow
What two main steps used to treat water from reservoirs?
trytr5y
When speciation complete?
When the two populations can no longer interbreed.
What is thought to be the two factors demonstrating sympatric speciation in the cichlids of Lake Victoria in East Africa?
-rapid speciation -sexual selection
Two main steps for building proteins from genetic information are?
transcrption and translation
What are the steps of organic evolution?
Organic evolution involves four main steps: variation in a population due to genetic mutations or recombination, natural selection where certain variations are favored based on their fitness, adaptation leading to changes in a population over time, and speciation where new species arise due to accumulated changes.
What happens when a lineage splits into two or more lines of descent.?
speciation
How can reproductive isolation lead to speciation?
Reproductive isolation separates the reproduction of one population into two populations. Over time after generations, the two separate populations start living and reproducing differently, so they evolve into two separate species, which is speciation (also known as divergent evolution). Reproductive isolation and speciation reduces gene flow.
