How was the mechanism of sympatric speciation among hemp nettles in nature verified experimentally? A) By simply creating unique hybrids under laboratory conditions B) By producing hybrids that were 98% fertile under laboratory conditions C) By producing experimental hybrids that could reproduce successfully with both parent species D) By producing experimental hybrids that formed fertile offspring with the naturally occurring hybrid E) By creating hybrids that reproduced through the F ₄ generation before dying from hybrid inviability

Question

Quizplus · Accepted Answer

The mechanism of sympatric speciation among hemp nettles was verified experimentally by producing experimental hybrids that formed fertile offspring with the naturally occurring hybrid. This approach demonstrated that the hybrids could integrate genetically with the populations they originated from, supporting the concept of sympatric speciation through hybridization and subsequent fertility.
