Question

speciaction resulted when the sperm of one population of sea urchin could only bind to eggs from certain females within the habitat.
a traumatic
b sympatric
c allopatric
d geographic

Explanation:

Sympatric speciation occurs when new species evolve from a single ancestral species while inhabiting the same geographic region. In this case, the sea urchin sperm binding to only certain eggs within the same habitat is an example of sympatric speciation due to reproductive isolation mechanisms within the same area. Allopatric speciation involves separation by a physical barrier, geographic speciation is related to physical - location - based separation, and traumatic is not a recognized type of speciation in this context.

Answer:

b. Sympatric
