Shortcut Methods
1. Chromosomal Basis:
Human sex determination is based on the XX-XY system, with specific sex chromosomes.
Females have XX chromosomes, while males have XY chromosomes.
2. Role of Sex Chromosomes:
The Y chromosome carries the SRY gene, triggering male development.
XX results in female development, while XY leads to male development.
3. Genetic Diversity:
Exceptions include atypical sex chromosome combinations due to genetic mutations.
Conditions like Klinefelter syndrome or Turner syndrome may result.
4. Environmental Factors:
Unlike some species, human sex determination is primarily genetic and not influenced by the environment.
5. Clinical Significance:
Understanding sex determination is crucial for medical genetics, fertility treatments, and reproductive medicine.
6. Ethical and Social Considerations:
Study of sex determination raises ethical questions related to gender identity and rights.
