The most immediate external effect of an egg being fertilized, is that a change occurs in the egg such that it either repels all other sperm, or at least is no longer accessible to them.
After the egg has been fertilized, it will then begin to grow into a fetus.
In humans, an egg can be fertilized within seconds of a male ejaculating semen. But sperm in semen can fertilize anytime up to about 72 hours after ejaculation.
The gametes, or "sex cells" - the sperm and ovum (egg) - become the fertilized egg (zygote) when they fuse.
A fertilized egg implants into the Uterus.
No
If an egg is fertilized by a sperm containing a Y chromosome, the egg would mature into a fetus which would then mature into a male offspring
The fertilized egg is called a fetus after 12 weeks of development.
After initial fertilization, the newly fertilized egg is called a zygote. Once it divides and become multicellular it is termed an embryo.
The sperm doesn't have to. Once the egg is fertilized it stays fertilized.
it isn't an egg its a baby which is very very small and had just been formed.
Once the egg is fertilized it remains fertilized until the egg is eaten, incubated or goes rotten and decays. It never goes back to being an unfertilized egg.
No. But you can get two eggs fertilized at the same time.
The fertilized egg implants and develops in the uterus.
Zygote
Sort of. A zygote is what one calls a female egg cell once it's been fertilized.
no because the egg should have been fertilized , a period is when the egg hasn't been fertilized and needs to leave the body
yes
zygote
Egg is a female ova (female gamete) which once fertilized becomes a fertilized egg.Each fertilized egg has an external protective membrane( hard shell in oviparous). Often two female gametes get fertilized and have a common protective membrane (hard shell in oviparous).This is why sometimes(rarely) an egg has two yolks inside.
