Differbetween
The similarity between internal fertilization and external fertilization is that the sperm fuses with the egg cell to form a zygote. 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.

What is the difference between internal and external development?
The difference between internal and external development is the fact that internal development refers specifically to sexual organs, while external development refers to the many physical changes that occur in an organism before it reaches sexual maturity.

Reproduction in Animals | Exercise
| Internal fertilization | External fertilization |
|---|---|
| Fusion of male and female gametes takes place inside the body. | Fusion of male and female gametes take place outside the body. |
| A female partner lays fertilized eggs or a fully grown young one. | The female partner lays unfertilized eggs. |
Which is better internal or external fertilization?
Internal fertilization has the advantage of protecting the fertilized egg from dehydration on land. The embryo is isolated within the female, which limits predation on the young. ... Fewer offspring are produced through this method, but their survival rate is higher than that for external fertilization.
What is the difference between external and internal fertilization quizlet?
External fertilization is when eggs are released by a female into the environment and later fertilized with a male's sperm. Internal fertilization is when sperm are deposited in or near a female's reproductive tract and fertilization takes place within the reproductive tract.
Which internal fertilization occurs in animal?
The offspring develops in the female and is born alive. This occurs in most mammals, some cartilaginous fish, and a few reptiles, making these animals viviparous. Internal fertilization has the advantage of protecting the fertilized egg from dehydration on land.
What is internal fertilization explain with example?
What is Internal Fertilization? Internal fertilization is the process of fertilization that occurs inside the body of an individual. It occurs mostly in land animals. ... Different animals have different methods of transferring the sperms. For eg., in mammals, reptiles, and some fish, this is done by copulation.
What is internal and external fertilization give examples?
Complete answer: Internal fertilization is the process when the syngamy (union of male and female gamete) occurs inside the female body after insemination using copulation. In contrast, External fertilization is the syngamy outside the female body, that is in the outer environment especially in water bodies.
What are internal and external fertilization?
External fertilization is a mode of reproduction in which a male organism's sperm fertilizes a female organism's egg outside of the female's body. 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.
What are the advantages and disadvantages of internal and external fertilization?
Increase chance gametes meet and greater change of successful fertilisation. More protection against outside environments and predators, and therefore a higher chance of surviving until birth. More selective of their mates. Less chance of desiccation of gametes.
