What are the advantages of internal reproduction?

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. Internal fertilization also enhances the fertilization of eggs by a specific male.

What are the advantages of external reproduction?

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.

What is a disadvantage of internal reproduction?

Disadvantages of internal fertilization are that there are lesser number of offspring produced at a given time because it is sometimes difficult for the male and female to come into intimate contact. Additionally, the risk of sexually transmitted diseases also increases.

What are the advantages and disadvantage of external fertilization?

(ii) Only a few gametes are released into the medium. (iii) Water is the medium of fertilization. It provides better chances of survival of gametes than internal fertilization. (iv) Offspring which develop from external fertilization has better chances of survival than those developed from internal fertilization.

What are disadvantages of external fertilization?

Disadvantages of External Fertilisation

A large number of gametes stays un-fertilised, and are subsequently wasted. There is no guarantee that the sperms and eggs will come into contact. Moreover, the chance of desiccation of zygotes or gametes are superior.

What is external fertilization and its disadvantages?

In external fertilization, eggs have fewer chances of fertilization. This can lead to the wastage of a large number of the eggs during this process. Further, there is an absence of proper parental care to the offspring, which results in a low rate of survival in the progress.

What are the advantages of internal and external Fertilisation?

Internal fertilization protects the fertilized egg or embryo from predation and harsh environments, which results in higher survival rates than can occur with external fertilization.

What is external fertilization Why is it disadvantages compared to internal fertilization?

Internal fertilisation occur in organisms like human and external fertilisation occur in organisms like frogs. Disadvantage if external fertilisation is that there is less chances of meeting of sperm and ova whereas in internal fertilisation there is more chances if fertilisation.

What is difference between external and internal fertilization?

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 2 advantages of internal fertilization?

Advantages of Internal Fertilization

The probability of successful fertilization is increased. The mates are selective. The chances of dehydration of gametes decreases. The young one is protected against predators and the outside environment and hence chances of survival are increased.

What is an advantage of internal fertilization quizlet?

It does not require a watery environment and is more efficient than external fertilization. For this reason, less energy is spent on producing large quantities of sperm and eggs.

What is external fertilization explain with example?

external fertilization is a case in which fusion of male and female gametes takes place in outside environment/ medium and not in the body of the female . for example, in case of frogs , fertilization takes place in water medium . the female releases eggs in the water at the same time sperms are released too.

What do you mean by internal fertilization?

Internal fertilization is the union of an egg and sperm cell during sexual reproduction inside the female body. ... Following fertilization, the embryos are laid as eggs in oviparous organisms, or continue to develop inside the reproductive tract of the mother to be born later as live young in viviparous organisms.

What is external fertilization short answer?

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. ... The release of eggs and sperm into the water is known as spawning.

Why is external fertilization bad?

Success of Fertilization

In external reproduction, animals disperse their gametes through a body of water. ... Many sperm and eggs die before achieving fertilization. The low success rate of external fertilization puts animals at a reproductive disadvantage compared to internal fertilization.
