Internal fertilization is the fusion of gametes that takes place inside the female body example mammals. External fertilization is the fusion of gametes that takes place in the external environment example fish and frogs.
Is a Bird an Example of External Fertilization?
Birds reproduce by internal fertilization where the egg is fertilized inside the female but the development takes place outside the body.
What is Internal Fertilization?
The process of fertilization takes place inside the body of the female where the sperm is ejaculated in the female reproductive tract of the female and it travels towards the oviduct where fertilization takes place.
What are the Examples of External Fertilization?
This type of fertilization takes place in fish and amphibians, some of them are salmon, codfish, starfish, sea urchin, and trout fish.
What is External Fertilization?
The fusion of the male sperm and female egg that takes place outside the female body usually in an aquatic environment is called external fertilization.
What are the Advantages and Disadvantages of External Fertilization?
External fertilization allows for a large number of offspring to be produced, enhancing species survival, but it also exposes eggs and sperm to predation and environmental hazards, reducing individual survival chances.
What are the 5 Examples of External Fertilization Animals?
Examples of animals that reproduce via external fertilization include fish, amphibians, mollusks, echinoderms, and many marine invertebrates like corals and sea urchins.
External Fertilization – An Overview
External fertilization occurs in fish, frogs, and certain invertebrates like sponges. External fertilization is the process of reproduction where the fusion of the male gamete and female gamete takes place outside the body in an external environment. This type of reproduction has various benefits as it has great biodiversity and the chances of survival are also higher. In this article, we will study the process of external fertilisation, examples, features and more.
