Retrogressive Metamorphosis Retrogressive metamorphosis refers to a specific type of metamorphosis observed in ascidians or tunicates, which are a type of urochordate. Metamorphosis is a process in which an organism undergoes a profound change in form during post-embryonic development, typically transitioning from a larval stage to an adult stage. In retrogressive metamorphosis, the larva possesses … Read more

The development of frogs follows a typical sequence of events observed in sexually reproducing organisms. It begins with the fertilization of an egg or zygote. The zygote then undergoes a series of divisions, dividing and re-dividing to form an embryo. The embryo is the earliest stage of development and remains within the egg or reproductive … Read more
