Which of the following pairings represents homologous structures?

Question

Quizplus · Accepted Answer

Homologous structures are structures that are similar in different organisms because they share a common ancestry. The ovary and testis are homologous structures because they both develop from the same embryonic tissue (gonadal tissue) and serve the same function in producing gametes (eggs or sperm). The labia majora and labia minora are also similar in function and location, but they are not considered homologous because they develop from different embryonic tissues. The clitoris and testis are not homologous structures because they have different functions and develop from different tissues. The ovary and scrotum are also not homologous structures because they have different functions and develop from different tissues.
