Abstract
Sex determination is an important biological process that determines the biological sex of an individual. It is determined by a variety of methods, which vary widely between species. This paper reviews the current knowledge on sex determination, including the processes involved in sex determination, the various methods used to determine sex, and the implications of sex determination in various contexts.

Introduction
Sex determination is a biological process that determines the sex of an individual. It is an important process as it determines the reproductive capabilities of an individual and is one of the most fundamental processes in biology. Different species use a variety of methods to determine sex, and the process of sex determination has implications for many aspects of biological research. This paper aims to review the current knowledge on sex determination, including the processes involved in sex determination, the various methods used to determine sex, and the implications of sex determination in various contexts.

Processes Involved in Sex Determination
Sex determination is a complex process, and the exact methods used to determine sex vary between species. In mammals, sex determination is primarily determined by the presence of sex-determining chromosomes, which are inherited from the parents. For example, in humans, a female typically has two X chromosomes while a male typically has one X and one Y chromosome. In other species, sex determination may be determined by environmental factors, such as temperature, or by the presence of a sex-determining gene.

Methods Used to Determine Sex
The methods used to determine sex vary between species. In humans, sex determination is typically determined by chromosomal analysis. This involves examining the chromosomes of an individual and determining their sex based on the presence of sex-determining chromosomes. In other species, sex determination is determined by different methods. For example, some reptiles rely on temperature to determine sex, while some fish rely on the presence of a sex-determining gene.

Implications of Sex Determination
Sex determination has implications for many aspects of biology. For example, the process of sex determination is essential for reproductive capabilities and is thus important for the survival of a species. In addition, the process of sex determination is important for understanding the evolution of species and for studying the diversity of life. Furthermore, the process of sex determination can be used to study the genetics of a species and to identify potential genetic disorders.

Conclusion
Sex determination is a complex process that determines the sex of an individual. The process of sex determination varies between species, and the methods used to determine sex also vary. Sex determination has implications for many aspects of biology, including reproductive capabilities, the evolution of species, and the study of genetics. This paper has reviewed the current knowledge on sex determination, including the processes involved in sex determination, the various methods used to determine sex, and the implications of sex determination in various contexts.
