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

Marine Evolution

Marine habitat is less explored, and hence, its biological diversity is far less known. The marine habitats are not constant due to their shifting nature, while the terrestrial habitats are more stable. Marine biology is the science that deals with the study of diverse marine species, their interactions, and behavioral characteristics.
