Study Notes
Sexual Dimorphism
- The key to sexual dimorphism lies in the development of the gonads, which acquire male or female morphological characteristics around the 7th week of development.
Gonadal Development
- The pair of primitive gonadal or genital ridges emerge around the 4th week of development.
- The initial content of these ridges consists of a mass of cells, including primordial germ cells, which have the potential to develop into either ovaries or testes.
SRY Gene
- The SRY gene, located on the Y chromosome, produces a transcription factor that plays a crucial role in initiating the development of testes.
- The SRY gene is responsible for triggering the process of testicular development, leading to the formation of male gonads.
