True or false. Is sympatric speciation, a physical barrier arises and separates two populations l, ending flow between them
timofeeve [1]
<h3><u>Answer;</u></h3>

The above statement is <u>False </u>

<h3><u>Explanation;</u></h3>
  • Speciation is an evolutionary process in which new species arise. There are three types of speciation, namely; sympatric, parapatric and allopatric speciation.
  • <em><u>Sympatric speciation is a pattern in which speciation occurs in the absence of a physical barrier to gene flow; ex. polyploidy arising in flowers.</u></em>
  • In an Allopatric speciation on the other hand, a physical barrier arises and separates two populations, ending gene flow between them and allowing reproductive isolating mechanisms to evolve so that later if the two groups come back into contact they will no longer be able to reproduce together, therefore making them different species.
