Ykromosomia
Ykromosomia is a hypothetical concept referring to a Y chromosome-like structure that may be involved in sex determination in a species other than humans. In humans, the Y chromosome plays a crucial role in male development, carrying the SRY gene which triggers the formation of testes. The term "Ykromosomia" suggests a similar genetic element in another organism that dictates the development of a male sex or a particular sex within that species.
The actual existence and specific function of a "Ykromosomia" would depend entirely on the genetic makeup of
Research into sex determination across the animal kingdom has revealed a wide array of chromosomal systems.
