a chicken egg looks the same fertilized or unfertilized, what it looks like inside, i don't know.
like a cell
because they fertilized egg split so they have the same DNA
A female will typically have six segments on her abdomen. If she wad fertilized, her stomach will swell and she will eventually lay an egg sac or ootheca. Even if she wasn't fertilized, she still may lay one, but it probably won't be viable.
Internal fertilization is like animals having sex....the egg is fertilized on the inside. External is when the egg is fertilized on the outside (like when frogs lay eggs and they need to be fertilized before they can hatch).
In the water like mosses
Baby finches aren't fertilized until they've become adult finches. Female adult finches, like most birds, are fertilized through something called a "cloacal kiss".
Frogs lay their eggs in large clusters so, it will look like a big ball made up of a bunch of smaller balls. The eggs will be clear, but if they are fertilized then they will be clear with a tiny black tadpole in the middle that will eventually take over the whole egg, then they'll be entirely black ( it's really the tadpole)
Twins only happen by chance, it is because when the ovum is fertilized it splits which will form into two babies, sometimes there are small changes but sometimes they look like clones.
They have roots just like other plants,and they do need to be fertilized.
No, it is not biologically possible for puppies to develop in a human uterus. The genetic makeup and environment needed for a fertilized dog egg to develop into a puppy are not compatible with the human reproductive system.
By Spoiled, I am going on you mean unfertilized. Most eggs will be fertilized, while the ones that are not, will turn white in most cases, and develop a fungus on them. The parents will pick those away usually.
Eggs sold in stores are typically unfertilized, meaning they will not develop into chicks even if incubated. Only fertilized eggs contain the genetic material needed for embryonic development and hatching. Commercially produced eggs for consumption are not fertilized.
