Solved Another Model of Speciation: Sympatric Speciation - Chegg
Another Model of Speciation: Sympatric Speciation Sympatric speciation does not require geographic isolation. In this model, populations can live in the same area, but may occupy different niches. A niche refers to an organism's way of life, which might include aspects of how it hunts, where it lives, and food preferences.
Solved Although sympatric speciation is considered to be - Chegg
Question: Although sympatric speciation is considered to be much rarer than allopatric speciation, it has been documented. Identify a sympatric speciation event in a fish, mammal or insect, and describe the geographic location and ecological conditions under which the event is hypothesized to have occurred.

Solved Often, sympatric speciation can involve polyploidy ... - Chegg
Question: Often, sympatric speciation can involve polyploidy, or extra sets of chromosomes.A type of polyploidy called alloploidy results when two related species hybridize, causing chromosome numbers to double.This allows chromosomes to pair up during meiosis, meaning that these organisms are fertile.This type of polyploidy is common in plants and results in new
