HOW DOES THE EMBRYO IN THE MOTHER’S WOMB UNDERGO SEX CHANGE AS ‘MALE’ OR ‘FEMALE’:
After the formation ‘embryo’ in the mother’s womb, its sex cannot change. Before formation of the fetal, there will be ‘egg yolk’ in the mother’s womb. Human cells have pair of chromosomes. But there is always ‘X-DNA String’ in the chromosome known as x chromosome. There is x or y chromosome in the man’s sperm. If the ‘egg’ joins with the man’s sperm, which has x chromosome and fetal is formed, that fetal grows as female. In each cell of the fetal, there will be two pairs of ‘xx’ chromosomes. At the same time, if there is y chromosome in the man’s sperm and joins with the ‘egg yolk’ and the fetal is formed, that egg-folk grows as ‘male’. In each cell of the man’s sperm, there will be pairs of xy chromosomes. It is known that the egg- folk are female, if there is xx in the chromosome and it is male, if there is xy chromosome. Therefore after the formation of the fetal, the sex will not change.
