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.
Eggs do not move, but sperm do. The sperm's tail allows it to move more quickly to the egg.
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.
No, in external fertilization, not all eggs are fertilized. The eggs are released into the environment and must be externally fertilized by sperm for fertilization to occur. Many eggs may not encounter sperm and therefore will remain unfertilized.
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.
No, human sperm cannot fertilize goldfish eggs. Sperm and eggs from different species are not compatible for fertilization due to genetic and biological differences.
-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.
