Life in the beginning

The zygote is the first cell created by the fusion of sperm and ovum but it does not stop there. The same cell contains 46 chromosomes or 23 pairs in its nucleus, besides the vesicules that act as food transporters and the mitochondria to produce energy. The cell, also, has a membrane that protects the integrity of the interior of the cell.

The number of chromosomes is constant in any particular species and in man the diploid number is 46 haploid 23; horse diploid is 64 haploid 32 and so on. The chromosomes (DNA) deoxyribonucleicacid, the building blocks of inheritance, contain all the genes that form the shape of the offspring: colour of eyes, the heart, the lungs, muscles, colour of skin and whether black or brown, curly or straight hair. All together they are called the phenotype (appearance) and genotype (the gene or combination of genes – known as polygenic).

The above is evidence that life begins immediately sperm and ovum fuse from male and female respectively, thus creating the first cell (the zygote).

In mitosis, chromosomes divide in two to provide identical cells. In meiosis and mitosis (identical) cells divide; they arrange for one chromosome of each homologous pair to go to opposite ends of the nucleus. This duplication of cells is done until death.

How is it possible not to admit that life begins from the creation of one cell (zygote)? Each cell duplicates until the final cell division to call gametes.

I do not want to trivialise the seriousness of the issue by trying to discuss the subject matter as though it were a simple explanation.
