The second polar body is expelled after fertilization as a result of the completion of meiosis in the oocyte. When a sperm fertilizes the egg, it triggers the final stages of meiosis, leading to the division of the oocyte into a mature ovum and the second polar body. This process ensures that the egg retains the correct haploid number of chromosomes while discarding the excess genetic material. The expulsion of the polar body is crucial for maintaining genetic balance in the resulting zygote.

When 2nd polar body is extruded in human fertilization?
The second polar body is formed during the second meiotic division of the oocyte after fertilization, typically about 12-24 hours after the sperm has entered the egg. This second polar body contains half the genetic material of the previous oocyte and is eventually degraded.
Does fertilisation take place during menstruation?
Fertilization typically occurs during ovulation when an egg is released from the ovary and is available to be fertilized by sperm. Menstruation is the shedding of the uterine lining if fertilization does not occur.
Where does the fertilisation take place?
in the vagina or woman's body
On a dolphin does fertilisation occur inside or outside the body?
internally
Does fertilisation have to occur in the body?
no but u hav to do it in ur mam
What is IFV?
In-Vitro Fertilisation i.e. fertilisation done outside of the body, before implanting the zygote into the womb. The common name for children resultant of fertilisation in this manner is "test tube babies", even though the actual fertilisation is usually done in a petri dish.
How long does pee stay warm after it is expelled from the body?
Urine typically stays warm for a few minutes after it is expelled from the body.
How long does pee stay warm for after it is expelled from the body?
Pee can stay warm for about 5-10 minutes after it is expelled from the body.
What temperature is pee when it is expelled from the body?
Urine is typically expelled from the body at around body temperature, which is approximately 98.6 degrees Fahrenheit (37 degrees Celsius).
How long does urine stay warm after it is expelled from the body?
Urine typically stays warm for about 5-10 minutes after it is expelled from the body.
What is type of fertilisation?
There are broadly 2 types of fertilisation - 1) Internal fertilisation - This mostly takes place in higher classes of animals like humans and mammals. In this the male transfers its gametes into the female body and the male gamete fuses with the female gamete inside the female body 2) External fertilisation - This is mostly seen in fishes. The male and the female both transfer their gametes into the external environment and the gametes fuse outside
What is the largest polar body of meiosis called?
First polar body
