Verified step by step guidance

Understand the concept of genital ridges: Genital ridges are structures that give rise to the gonads (testes or ovaries) during embryonic development. They are formed from intermediate mesoderm and are influenced by genetic and hormonal factors.

Review the timeline of embryonic development: Embryonic development is divided into weeks, with specific events occurring at different stages. For example, organogenesis begins around the 3rd week, and major systems start forming in subsequent weeks.

Identify the week associated with genital ridge formation: Genital ridges begin to form during a specific week of development, which is critical for the differentiation of the reproductive system.

Compare the options provided: The options given are 5th, 9th, 7th, and 3rd weeks. Use your knowledge of embryology to determine which week aligns with the formation of genital ridges.

Confirm the correct answer: Based on embryological studies, genital ridges are formed early in the 5th week of embryonic development. This is when the intermediate mesoderm starts differentiating into structures that will later develop into gonads.
