How is the human reproduction?

The human reproduction occurs when fusion the male and the female reproductive cells gametes. This fusion is when the sperm enter in to the ovule and fertilized a woman, to create a new cycle of life.

This fertilization is made by the female and male reproductive organs during the sexual act join his respective gametes transmitting their characteristics between 23 pairs of father´s chromosomes with the other 23 pairs of the mother´s chromosomes forming 46 chromosomes that have all the genetic information of his parents.

Why the human reproduction?

Because the entire living organism need perpetuate his specie, the species that more adapt will survive and the others start to extinguish.

Between his reproductions they can improve or evolve their ability to survive in their environment and become in better species.

With the reproduction the people can keep the life cycles good and enjoy all stages of growth, reproduce, care for their children to finally die.

Reflection of this work

Now I know that the reproduction is very important for the human and all the species because if we don`t reproduce the other generations are going to start to disappear and finaly there are not more humans.
