It is pronounced as /ˌhɛtərəʊˈkrəʊniə/, with the stress on the fourth syllable. The initial "h" is silent, and the "ch" sounds like a "k".

HETEROCHRONIA Meaning and Definition

  1. Heterochronia, also known as chronoanomaly, is a term used in biology and medicine to describe an abnormality or variation in the timing or rate of development or growth in an organism or its parts. It refers to a condition where there is a deviation from the usual or expected sequence and timing of events during development.

    In the context of embryology, heterochronia may manifest as changes in the timing of specific developmental processes, such as the appearance or disappearance of certain structures or the initiation of organogenesis. These variations can occur during early embryonic development or throughout the lifespan of an organism.

    Heterochronia can also refer to differences in the rate at which certain traits or characteristics develop or change. For instance, it may describe discrepancies in the timing of sexual maturation, skeletal development, or the aging process within a population. Such variations can be caused by genetic factors, environmental influences, or a combination of both.

    In ophthalmology, heterochronia specifically refers to a condition where the iris of one eye differs in color from the other. This condition is commonly referred to as heterochromia iridis and can occur due to variations in the amount, distribution, or type of pigment in the iris.

    Overall, heterochronia encompasses various aspects of timing and developmental processes, providing a term to describe deviations from the typical patterns observed in biological systems.

  2. The origin or development of tissues or organs at an unusual time or out of the regular sequence, as the development of embryonal tissue after birth.

Etymology of HETEROCHRONIA

The word "heterochronia" originates from the combination of two Greek roots: "hetero-" meaning "different" or "other", and "chronos" meaning "time". These roots combine to form "heterochronia", which is a term used in biology to describe a condition where two related organisms or structures develop or mature at different rates.
