An egg only allows one sperm to enter and is fertilized by that one sperm: 2 cannot enter.
A sperm and an egg.
Yes, it is possible for 2 sperm to reach the egg, however only one will fertilize the egg. It isn't uncommon for more than 2 to reach the egg, depending how are along the egg is down the falopian tube. And how much sperm was ejaculated.
Sperm typically takes several hours to travel and meet the egg in the fallopian tube after ejaculation, so it is unlikely that a sperm can reach and fertilize an egg in just 2 seconds. The journey of the sperm to the egg is a complex process that requires time.
Sperm and egg.
sperm and egg
It is important that only one sperm fertilizes an egg to ensure the correct number of chromosomes in the resulting embryo. If multiple sperm were to fertilize the egg, it would lead to an abnormal number of chromosomes, resulting in genetic disorders and potential miscarriage.
Only one sperm fertilises an egg in normal cases, abnormally there are chances of fertilization by 2 or more sperm cells but such a zygote usually does not survive.
a zygote is a fertilized egg. one that has formed by the fusion of an egg cell and a sperm cell
2 sperm cells hit the egg
Two types of sex cells are> Sperm (in males)> Egg or ovum (in females)Sperm is produces in the testes.Ovum or egg is produced in the ovaries.Source(s):
Sperm enters the egg; egg turns because the 2 cells egg and sperm use mitosis to make more cells.
after an egg is penetrated by a sperm, the egg and sperm nuclei fuse to form a single nucleus. within 2- 5 minutes after sperm penetration, a fertilization membrane forms beneath the jell coat to prevent the entry of additional sperm.
