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).
Allotropes are different forms of the same element. Different bonding arrangements between atoms result in different structures with different chemical and physical properties. Allotropes occur only with certain elements, in Groups 13 through 16 in the Periodic Table.This distribution of allotropic elements is illustrated in Figure 1.ifferent bonding arrangements between atoms result in different structures with different chemical and physical properties.
