Verified step by step guidance

Understand the role of the SRY gene: The SRY (Sex-determining Region Y) gene is crucial for initiating the development of male characteristics in an XY individual. It is located on the Y chromosome and triggers the formation of testes, which produce male hormones.

Consider the genetic implications: In a typical XY individual, the presence of the SRY gene leads to the development of male reproductive organs. Without the SRY gene, the pathway for male development is disrupted.

Explore the developmental consequences: Without the SRY gene, the default pathway for sexual development is female. This means that an XY individual missing the SRY gene will likely develop female characteristics.

Evaluate the potential outcomes: The absence of the SRY gene in an XY individual can lead to the development of female reproductive organs, as the body does not receive the signals to form male organs.

Summarize the likely outcome: Given the absence of the SRY gene, the individual will develop as a typical female, as the genetic and hormonal signals for male development are not present.
