Describe with appropriate examples the role of environment in the determination of sex.
In genetics, the determination of sex is primarily governed by the genetic makeup of an organism, particularly through sex chromosomes. However, the environment can also influence sex determination in certain species, shaping sexual differentiation and expression through various mechanisms. This process can be observed in different organisms, including mammals, reptiles, fish, and even some plants, with environmental factors influencing either the genetic pathways of sex determination or the physical characteristics that determine sex.
In most mammals, sex is determined genetically, with two types of sex chromosomes: X and Y. The presence of two X chromosomes (XX) results in female development, while the presence of one X and one Y chromosome (XY) leads to male development.
