DISPERMIC Meaning and
Definition
-
Dispermic is an adjective that refers to the condition or occurrence of having two distinct genetic parents. The word is derived from the combination of the prefix "di-", meaning two, and "sperm", which relates to seed or reproductive cells in sexual reproduction.
In the context of biology, dispermic specifically characterizes the fertilization process in which two different sperm cells from separate male donors fuse with two separate eggs from the female. This is a relatively rare form of fertilization that may occur spontaneously or through assisted reproductive techniques, such as artificial insemination or in vitro fertilization.
Dispermic fertilization can result in the creation of dizygotic (fraternal) twins, where each individual develops from a separate fertilized egg. In this case, each offspring will have its own unique genetic composition, distinct from both parents and each other. This diversity in genetic makeup typically leads to the siblings having different physical and possibly behavioral characteristics.
It is worth noting that dispermic fertilization is in contrast to monospermic fertilization, which involves the fusion of a single sperm with an egg during fertilization. Monospermic fertilization is far more common in most species, including humans.
Overall, dispermic describes the phenomenon of having two different sperm cells fertilizing two separate eggs and plays a crucial role in the formation of dizygotic twins and the genetic diversity among siblings.
Etymology of DISPERMIC
The term "dispermic" seems to be a highly specific and technical term with limited usage in science, particularly in the field of genetics. It is derived from a combination of two root words:
1. "Di-" which is a prefix derived from the Greek word "di-", meaning "two" or "double".
2. "Spermic", which relates to "sperm", originating from the Greek word "sperma", meaning "seed" or "sperm".
Therefore, "dispermic" can be understood as a compound word combining the idea of "two" or "double" with "sperm" or "seed". However, without a more specific context, it is challenging to determine the exact usage or meaning of the term. It is advised to consult relevant scientific literature or experts for further clarification on the intended definition within the specific scientific context.
