Question

How many sperm enter an egg?

Answer 1

Sperms

1. Most animals generate sperm, also known as a spermatozoon, a type of male reproductive cell.
2. Sperm is produced by the male reproductive system in the seminiferous tubules of each testis.
3. DNA is located in the sperm's head, and when it combines with DNA from an egg, a zygote is formed.
4. A woman's egg can be fertilized with just one sperm.
5. A sperm's entry causes the zona pellucida layer to alter and prevents the entry of other sperm.
