What are the Differences between Dominant Factor and Recessive Factor?
| Dominant Factor or Allele | Recessive Factor or Allele |
| Expression. It is able to express its effect even in the presence of recessive factor. | Recessive factor is unable to express its effect in the presence of dominant factor. |
| Protein. It produces an effective protein for expressing its effect. | It produces a defective or incomplete protein. |
What are the Differences between Homologous Organs and Analogous Organs?
| Homologous Organs | Analogous Organs |
| External Appearance. It is usually different. | It is generally similar. |
| Function. They generally perform different functions | They have a similar function. |
| Basic Plan and Origin. They are similar. | They are different. |
| Evolution. Homologous organs show adaptive radiation or divergent evolution. Example. Forelimbs of Frog, Lizard, Bird and Human | Analogous organs show convergent evolution. Wings of Insects, Bat and Bird. |
