DIZYGOTIC TWIN Meaning and
Definition
-
A dizygotic twin, also known as fraternal twin, is a type of twinning characterized by the simultaneous conception and development of two offspring from two separate eggs fertilized by two different sperm cells. Dizygotic twins are formed when a woman simultaneously releases multiple eggs during ovulation, each of which is fertilized by a different sperm cell. Consequently, dizygotic twins share approximately 50% of their genetic material, just like any other siblings born at different times.
Dizygotic twins can be of the same or different sexes, and they generally have different physical characteristics and distinct sets of genetic traits. This is due to the fact that each twin inherits a unique combination of genes from their parents, resulting in slight variations in their appearance and other hereditary traits. In terms of appearance, dizygotic twins may share certain traits but often display different hair color, eye color, and facial features.
Compared to monozygotic twins (identical twins), dizygotic twins tend to have a lower degree of genetic similarity and a higher likelihood of differences in their developmental processes and genetic variations. Dizygotic twinning is more common than monozygotic twinning and is primarily influenced by genetic and environmental factors. Studies have shown that certain factors such as maternal age, family history of twinning, and fertility treatments may increase the chances of conceiving dizygotic twins.

Etymology of DIZYGOTIC TWIN
The term "dizygotic twin" is derived from two different sources.
First, "twin" comes from the Old English word "twinn", meaning "consisting of two". It has roots in other Germanic languages as well.
Second, "dizygotic" is a compound word consisting of two Greek parts. "Di" comes from the Greek word "di-" meaning "two", and "zygos" means "yoke" or "pair". Hence, "dizygotic" implies "two yoked" or "two paired" twins.
Overall, the etymology of "dizygotic twin" illustrates the combination of Old English and Greek origins to describe twins formed from two separate eggs fertilized by different sperm.
