... sperm to allow only the best one to unite with the egg. I am amazed that I am a product of a sperm and an egg. Out of the millions of millions of sperm, only one made it to unite with the egg. It is hard to believe that this tiny, DNA carrying cell can combine with an egg of a female to produce a human being. As I think about this process ... , I realized that life began as a competition and I came out to be the victor. Once the egg has been fertilized, it is then called the zygote. This ... from microscopic dividing cells into a complete, living, and breathing human being. I will never...

... generation. As the triumphant sperm reaches the egg the sperm begins to burrow its head to the egg to exchange genetic information. Inside the cells, one chromosome of each pair is the same to one in the sex cell the father contributed and the other in the ... same pair is identical to one of the sex cells the mother contributed. Thus, there are 23 chromosomes which carry the father's hereditary contribution and 23 from the mother's hereditary contribution making 46 chromosomes or 23 pairs of chromosomes.

... a person, but what else can it be. Once the sperm and egg unite, the 23 chromosomes of each are brought together to form one cell with 46 chromosomes. Once this cell with 46 chromosomes is formed, that one cell has all of the DNA, the entire genetic code that makes up a human being. Everything which ... constitutes a human being is in that one cell from conception on it just takes time ... every person has their own morals and views. The beginning of life should be a scientific and biological issue. Science says that once the 46 chromosome cell is formed, the unborn fetus a living, dev...
