The word "merogeny" is not a commonly used term and may not be familiar to many readers. Its correct spelling is /mɛˈrɒdʒəni/ with emphasis on the second syllable. The word is derived from the Greek words "meros" meaning "part" and "genesis" meaning "origin" or "creation". It refers to a type of embryonic development in which the zygote divides partially to form multiple offspring. While not frequently used, a knowledge about merogeny is important for individuals interested in biology and embryology.
