Which of the following is not accurate? Group of answer choices Epigenesis is consistent with how frog development proceeds Epigenesis is no longer the favored hypothesis to explain animal development Epigenesis replaced preformation as the favored hypothesis for animal development Epigenesis holds that the gametes do not contain very small animals inside them

Step 1
The terms "epigenesis" and "preformation" are central to the discussion of animal development. Epigenesis suggests that development is a gradual process where the organism develops from an undifferentiated state, while preformation posits that organisms develop Show more…

The preformationism hypothesis suggested that inside the egg or sperm is a tiny adult called a homunculus. It was hypothesized that the homunculus simply enlarged during development. Select the evidence that disproves the early heredity hypothesis of preformationism. Zygotically expressed genes regulate development in a sequential manner. Genes expressed in the developing embryo interact with each other. A fruit fly forms from an early embryo that lacks distinct anterior and posterior regions. Maternal-effect genes do not affect embryonic development. Maternal-effect genes can affect embryonic development.

Aristotle considered two opposing theories of development: preformation and epigenesis. Describe what is meant by these two terms; refer to the concept of the 'homunculus' when describing preformation, and to the art of origami in describing epigenesis. Which of these two theories better describes our current view of development?
