Question about Neoteny

In Reply to: Question about Neoteny posted by MCBond on May 01, 2003 at 22:59:09:

:I am curious to know wether neoteny is environment related, gene related or a mixture of the two. In Barron's Newts and Salamanders, it states "Neotony is usually associated with cold waters and may occur occasionally or always depending on the species and the population."
:If two sexually mature animals have both stayed neotonic because of climatic reasons, will their offspring be neotonic as well? Is it possible for the offspring of neotonic parents to morph? For that matter, is it possible for long term neotonic animals to morph on their own, perhaps due to environmental or habitate changes?
:Thanks

Neoteny is very complex with both genetic and environmental causes. Some populations show neoteny, others of the same species don't. Cold waters certainly tend to induce it in susceptible species, as does lack of iodine (stimulates pituitary hormones).
