Polyploidy is to have two copies of each chromosome, itâ??s important in crossbreeds to allow reproduction. Polyploidy speciation requires altering a chromosome number; itâ??s more common in plant species.

Any species with a multiple set of chromosomes is?
Organisms that have more than two complete sets of chromosomes are said to be polyploid. This often occurs in plants.
In which area would a population be geographically isolated?
An Island
How is sympatric speciation similar to allopatric speciations?
allopatric speciation happens when a physical barrier divides two populations of the same species and sympatric speciation happen when no physical barrier divides the member of a population, but methods such as polyploidy (chromosome doubling) do not let the members of the species have fertile offspring, 2 species are formed (the parental "normal" species and the divergent species "polyploids"). Remember that a species is defined as a population that when mated with one another produce fertile offspring. A polyploid and a parental organisms can not produce fertile offspring together so they become two different species and speciation is said to have occurred.
What happen when organisms populate a new area and are isolated geographically from other populations of the same species?
The species will eventually evolve to be similar, but not exactly like the main species.
What occurs when water molecules diffuse through a membrane?

Which type of speciation occurs among the Galapagos islands finches?
allopatric speciation

Sympatric Speciation
What characterize the speciation in new areas such as a recent formed island?
Rapid speciation occurs as populations adapt to the environment. (Novanet)
