Mammals such as dogs, chimpanzees, whales or humans have sexual reproduction with internal fertilization and oogamy, they are also viviparous animals, so embryonic development will take place in the womb. For example amphibians, algae and fish, etc. External Fertilization The dissimilarity is that in internal fertilization, the fusion occurs inside the body of the organism while in external fertilization, the fusion occurs outside the body of the organism. External fertilisation is a method of reproduction in which a male organism's sperms fertilise a female organism's eggs, but outside the female body. Salmon, cod, trout, and char are all examples of the fish that externally fertilize. It is contrasted with internal fertilization, in which sperm are introduced via insemination and then combine with an egg inside the body of a female organism.

Fertilization is the most important event that takes place in sexual reproduction.In other words, it is the vital process that . (i) The male and female gametes are formed and released simultaneously. . Descriptive external fertilisation examples are that of salmon, trout fish and codfish. Humans provide an example of the former whereas seahorse reproduction is an example of . Medium. External fertilization- fertilization of two different gamets . External fertilization refers to the fusion of male gametes and female gametes taking place from the outside of the body. What is means. External fertilization has greater synchronisation and is a much simpler process as compared to that of internal reproduction.

It is contrasted with internal fertilization, in which sperm are introduced via insemination and then combine with an egg inside the body of a female organism. It is a specialization for the protection of egg, but it depends on the birth method . Another type of external fertilization involves the male of the species shedding his sperm over eggs laid in a nest by the female. External fertilization is a kind of fertilization where eggs are released into the environment in order to be fertilized by the male.

Viviparity: In this mode of internal fertilization, the young ones develop inside the mother and receive nourishment through the placenta. Moisture in the environment keeps the gametes from drying out. This can occur either inside (internal fertilization) or outside ( external fertilization) the body of the female.

Which is an example of external fertilization? External and Internal Fertilization. What is external fertilization example? Advantages of External Fertilization. (iii) Water is the medium of fertilization. Offsprings have a high chance of survival. External fertilization in animals usually occurs in water or in damp areas in a process called spawning. For example, the Chinook salmon can deposit up to 14,000 eggs in a nest. Beside above, what is external fertilization explain with example? The main difference in between internal and also external fertilization is that internal fertilization occurs within the female biology whereas exterior fertilization occurs exterior the woman organism.
