MICHAEL ALLABY "stasipatric speciation Here we are discussing various differences between allopatric and sympatric speciation. Fruit flies are a primary example of artificial speciation. It seems to consist of two components, an allopatric one and a “semigeographic,” or parapatric one. In sympatric speciation, the evolution of new species takes place from a single ancestral species. Stasipatric speciation is unlikely under population genetic theory; ... a substantial portion of the total genetic variation in our samples was not explained by the chromosomal variation. The allopatric speciation is also known as geographical speciation. productionrespiration ratio, Stashower, Daniel 1960- (Daniel Meyer Stashower). However, the date of retrieval is often important. Peripatric speciation has been researched in both laboratory studies and nature. First, in stasipatric speciation the effectiveness of a chromosomal rearrangement in producing afertility barrier was the same during its establishment in a population and later as a postmating reproductive isolating mechanism.
