For each scenario given, decide whether allopatric or sympatric speciation would be the likely result.
1:Some female African cichlids
only mate with blue-colored
males, while others only
mate with red-colored males.
2:An island splits in two and
the halves drift apart,
separating a population of
native birds.
3:The development of a
road divides a population
of rabbits.
4:Some beetles in a population
only mate at night, while
others only mate during
the day.
5:In a population of mice,
some mice only eat fruit
while others only eat seeds.
