One egg, one sperm.
That is a good question. Both egg and sperm has the same number of chromosomes. But then the size of the egg is very big compared to sperms. Here the egg has lot of food material stored in them. that is necessary for cell multiplication after the conception. sperms has to run fast for fertilization. You can not run fast with some heavy weight on your back. Also the number of the sperms is very high and so many big sperms will create the problem of accommodation in the semen.
To have twins, it's just two. whether they're identical or not depends on if they're two girls, two boys, or one boy and one girl. To have twins, it's just two. whether they're identical or not depends on if they're two girls, two boys, or one boy and one girl.
there are two types of twins-- fraternal and identical. Fraternal twins are genetically unique, and they usually have physical differences. Identical twins are identically identical, such as a clone, and have exact physcial characteristics, excluding weight and scars etc.
Only one sperm will enter the egg. It is known as fertilisation.
Most 99.99% of the time only one is supposed to.

A female salmon can produce thousands to millions of eggs, while a male salmon can produce billions of sperm. The number of eggs and sperm produced can vary depending on factors such as the age and size of the fish.
What is necessary is sperms of male turtle . So if there is presence of undamaged sperms in surrounding water then female can be fertilized .
Only one.
only one
Because so many of their young are eaten by other critters. The idea is that they create a lot of eggs in hopes that at least a few will survive.
