What are advantages of internal 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. Internal fertilization also enhances the fertilization of eggs by a specific male.

What are the advantages and disadvantages of external fertilization?

External fertilization in an aquatic environment protects the desiccation of eggs. Broadcast spawning leads to higher genetic diversity due to a larger mixing of genes within a group. The chances of survival of the species also increase.

What is the advantage of internal fertilization over external?

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 disadvantages of fertilization?

Fertilization is a process of fusion of male and female gamete to produce a zygote. Disadvantages of fertilization are as follows: ... Fertilization is a time consuming and complex process.

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 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 is external fertilization and internal 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 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 internal fertilization explain with example?

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 possible benefits 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.

Is Mosquito internal or external fertilization?

Fertilization in mosquitoes occurs as eggs are oviposited (Fig. ​ 2).

Is internal fertilization asexual?

In asexual reproduction, an individual can reproduce without involvement with another individual of that species. ... During sexual reproduction, the male gamete (sperm) may be placed inside the female's body for internal fertilization, or the sperm and eggs may be released into the environment for external fertilization.

What are the advantages of double fertilization?

The first advantage of double fertilization in plants is that the plant does not invest energy in seed nutritive tissue until after an egg is fertilized. The second advantage is that the endosperm nucleus is very active and divides rapidly. it forms the nutritive tissue very quickly.

What is external fertilization example?

Descriptive external fertilisation examples are that of salmon, trout fish and codfish. Both the female and male release their eggs and sperms respectively into the water where they diffuse and fertilize. In the list of external fertilization examples, aquatic animals such as mammals and sharks are exceptions.

What is external fertilization give examples?

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.
