The sperms are what in origin?
Correct answer: B. Mesodermal
- A. Ectodermal
- B. Mesodermal
- C. Endodermal
- D. None of these
Explanation
Option B is correct since the sperm and egg cells are produced from the germs cells- spermatozoa and oogonium present inside the 'testes' and 'ovaries' respectively. Since the 'gonads' and the 'germ cells' have a mesodermal origin, sperm and egg cells also have a mesodermal origin. sperm cells are derived from germ cells, which in turn are formed from the mesodermal layer of the developing embryo. Sperm cells are not derived from the ectoderm or endoderm.
