DefinedMeaning talk:egg (1100)

From OmegaWiki
Jump to: navigation, search

The current definition, "A large, female sex cell enclosed in a porous, calcareous or leathery shell, produced by birds and reptiles" can be improved, as it refers only to eggs from certain types of animals. There are actually two separate concepts to be defined: 1) "The zygote, resulting from fertilization of the ovum and covered with a protective shell, that is expelled from the body and permitted to develop outside the body until the developing embryo can survive on its own." 2) "The female gamete of an animal or plant, capable of fusing with a male gamete to produce a zygote." --InfoCan 19:18, 2 April 2012 (CEST)

Or perhaps:

"A large, round body produced by the female of birds and other animals which can generate a new individual if combined with a male reproductive cell."

The description of the shell is not a defining feature. Reptilian eggs have a leathery surface, fish eggs are gelatinous, insect eggs have a firm membrane. --InfoCan 22:14, 1 June 2012 (CEST)

This DM is only about the meaning "1" that you identified above.
I thought we had already a DM for "2", but apparently not. So I created it DefinedMeaning:ovule_(1385877).
I agree that if we include fishes and insects (which seems reasonable), the definition needs to be changed.
I am not sure whether an egg needs to be fertilized to be called an egg. There are species that expel the eggs which are then fertilized later on (some fishes), and ducks (and hen?) can lay an egg without prior fertilization.
So, something like "A large, round, female sex cell produced by [some?] birds, reptiles, fishes and insects that is expelled from the body and wherein an embryo can develop until it can survive on its own" ? --Kip 22:56, 1 June 2012 (CEST)

I think we should split this into three terms:

  1. In daily usage, for domestic fowl, we use the word "egg" imprecisely, whether it is fertilized or not, and often think of it simply as a food source: "A large, round structure covered by a hard or leathery shell, produced by a domestic fowl, that contains either an ovum or an embryo.".
  2. In the more precise sense of unfertilized egg: "(Biology) A sex cell produced by the female animals that can be fertilized by male sex cell to produce a new individual."
  3. In the more precise sense of fertilized egg: "(Zoology) A structure resulting from fertilization of the ovum, which is expelled from the body and in which the embryo develops until it can survive on its own."
