Question

While conducting field studies on a chain of islands, you decide to
karyotype two phenotypically identical groups of turtles, which are
found on different islands. The turtles on one island have 24 chromosomes,
but those on another island have 48 chromosomes. How
would you explain this observation? How do you think the turtles
with 48 chromosomes came into being? If you crossed the two
types of turtles, would you expect the offspring to be phenotypically
normal? Would you expect them to be fertile? Explain.
