They both contain 1/2 the number of chromosomes of a "normal" cell.
They don't contain the necessary organelles to survive on their own.
They both can create a zygote (if they are combined).
Both are gametes and are produced by meiosis's.
The same way all eggs are fertilised - with sperm from a male.
Frogs lay their eggs as they mate. The female releases her eggs and the male sprays his sperm over them at the same time.
No. They have to come from the same egg and sperm to have the same DNA (and be identical). Fraternal twins are non identical twins and come from two separate eggs.
The Correct Answer Is Cross-Pollination Save
During spawning the coral releases both eggs and sperm into the water at the same time. Fertilization occurs in the water.
No, girls do not have sperm. Sperm are the male's reproductive cells. Only men have sperm. Girls (females) have eggs instead.
It's depending on the number of eggs released by the female. It is the same in humans, thought the twins instances do occur. The male releases millions of sperm that then try to find the eggs once released.
-They produce a large amount of gametes -They synchronize spawning so there are both sperm and eggs present at the same time -Males usually spawn upstream so sperm gets carried to eggs -Eggs adhere to the spines of the female urchin to keep them from floating away to make it easier for sperm to reach them
Nothing different happens to sperm when you're on or off Depo Provera.
No, for example human eggs are fertilized internally, as well as many other animals.
In the cells that will divide to become eggs or sperm (or the eggs or sperm themselves).
Clams breed by releasing their eggs and sperm into the water at the same time. Once this is done, the eggs are fertilized as they float in the ocean, becoming eggs and then eventually turning into tiny clams.
