Where are human eggs usually fertilized in the process of reproduction?
Human eggs are usually fertilized in the fallopian tubes during the process of reproduction.
Is meiosis necessary before fertilization Can occur?
Yes, meiosis is necessary before fertilization can occur because meiosis is the process by which gametes (eggs and sperm) are formed. During meiosis, the cell's chromosome number is halved, so that when the egg and sperm fuse during fertilization, the resulting zygote will have the correct number of chromosomes.
Why human egg is smaller than hens egg?
Human eggs are smaller than hen's eggs because they have different functions. Human eggs are designed for fertilization and subsequent implantation in the uterus, while hen's eggs are meant to provide nutrients for a developing chick. Therefore, the size difference is due to their respective biological purposes.
What is it called when sperm and eggs are released into sea water and chance contact results in fertilization?
This process is known as external fertilization. It is a method of reproduction where gametes (sperm and eggs) are released into the environment, usually water, and fertilization occurs outside of the organism's body. This is common in aquatic species like fish and amphibians.
What is the difference between external fertilization and internal fertilization?
External takes place outside the female, as with fish eggs on which the male fish places his sperm. Internal fertilization, in plants and animals, takes place within the organism's structures, where the gametes are joined. In humans, in vitro fertilization (i.e. test tube babies) is a form of external fertilization in that it bypasses the normal occurrence in the fallopian tubes, and then directly implants the fertilized egg(s) in the uterus.
What is the science definition of fertilization?
Human fertilization is the union of human eggs and sperm usually occurring in the ampulla of the uterine tube.
Which flower part does fertilization of the eggs occur and the seeds develop?
the ovule.
Where does fertilization of human eggs take place?
fallopian tube
How does the number of eggs relate to the type of fertilization?
Usually, it doesn't. The only thing that would be different is that internal fertilization, there is less eggs because they are protected in the mother's body. The external fertilization, there is more eggs because of the lesser chance of survival
What adaptations in aquatic animals help ensure that external fertilization will occur?
produce more eggs
Are all eggs fertilized in external fertilization?
No, in external fertilization, not all eggs are fertilized. The eggs are released into the environment and must be externally fertilized by sperm for fertilization to occur. Many eggs may not encounter sperm and therefore will remain unfertilized.
How does fertilization occur in bony fish?
Fertilization can happen either inturnaly in a fish that produces both eggs and sperm or exturanly with a fish that produces on sperm.
How long does it take a hen to lay eggs after fertilization?
More than an average human
Is an egg from a duck fertilized upon laying if a male is present and has mated with the female or does fertilization occur after laying?
As with chicken eggs, fertilization occurs prior to laying the egg. It takes a week after mating for a duck's eggs to be fertile.
Is aves internal or external fertilization?
Aves, or birds, typically exhibit internal fertilization. In this process, the male bird transfers sperm to the female bird's reproductive tract before the eggs are laid. This adaptation allows for the fertilization of eggs to occur inside the female's body, which can enhance the likelihood of successful development of the embryos. After fertilization, the female lays eggs that develop outside her body.
Where does the fertilization takes place?
Depending on the animal, fertilization of eggs can occur externally or internally. With internal fertilization...the sperm and egg generally combine in the fallopian tubes.
Why testis and ovary are important in human reproduction?
Testis and ovary are important in human reproduction because they produce gametes (sperm and eggs), which are necessary for fertilization to occur. The testis produces sperm through the process of spermatogenesis, while the ovary produces eggs through the process of oogenesis. Without these gametes, fertilization and ultimately reproduction cannot take place.
