Gametogenesis is to spermatogenesis and oogenesis as GONADS ARE TO TESTES AND OVARIES.

Explanation:

Gametogenesis is a process where a diploid cell undergo meiosis cell division and differentiation to produce haploid cells or gametes.

Gametogenesis is in two parts which are spermatogenesis and oogenesis.

Spermatogenesis is a process where a diploid cell produce or form haploid sperm.
