Homology similarity

Web7 apr. 2024 · “Homologous,” in biology, means a similarity in internal or chromosomal structures. With internal structures, homology indicates organs that have similar positions, structures, or evolutionary origins. It’s important to note, however, that organs do not have to have the same function to be homologous. Web9 mrt. 2024 · Internal homology Gonads descent There are only a few similarities with respect to the internal reproductive organs of males and females. The gonads of both genders undergo descent from their initial position to different degrees. Testicular descent is far more dramatic and results in the male gonads being located outside the body cavity.
