explain the difference between internal and external fertilization and the advantages

Both gametes are deposited into outside surroundings. Organisms that are involved in internal fertilisation can produce a lesser number of offspring. Organisms that perform external fertilisation can produce a greater number of offspring.

What are the differences between internal and external fertilization?

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 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.

What are the advantages and disadvantages of external fertilization?

Also, it is easier to find mates as the gametes just need to be released and can drift away with wind or water. This results in greater genetic variation. The disadvantages however, are that there is reduced chance of survival from predators and harsh environments.

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.

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 are the advantages of internal fertilization?

When a sperm fertilizes an egg within the female, it is known as internal fertilization. The advantages of internal fertilization are that the fertilized egg is protected from predators and harsh environments, thus ending in higher chances of survival. Also, there is a lesser chance of desiccation of gametes.

What is the major disadvantage of external fertilization?

Disadvantages of external fertilization include a reliance on water and the large amount of wasted sperm and eggs that never reach a corresponding gamete, even when the organisms releasing the eggs and sperm are in close proximity. Additionally, the eggs released can have no shells, as these would stop sperm.

What are the pros and cons of internal fertilization?

Advantages & Disadvantages of Internal and External Reproduction

• Increase chance gametes meet.
• 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.

What is external fertilization short answer?

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 of the following is an advantage of external fertilization?

Advantages of External Fertilization

It results in increased genetic variations. It produces a larger number of offsprings. The gametes released can drift and therefore it is easy to find mates.

Why do fish use external fertilization?

External fertilization in an aquatic environment protects the eggs from drying out. Broadcast spawning can result in a greater mixture of the genes within a group, leading to higher genetic diversity and a greater chance of species survival in a hostile environment.

What is advantage of asexual reproduction?

What are the advantages and disadvantages of Asexual Reproduction? Advantage: Quick Reproduction, Requires no mate, only 1 parent needed. Disadvantage: Can not adapt to change, no genetic diversity, DNA is exactly the same as parent.
